“Republican cuts kill.”

That was the Left’s hideous accusation against the GOP, as this Ebola-dominated week began. As the weekend approaches, this ugliest of liberal smears now is engulfed in flames. Those who peddled it are exposed as shameless liars. Had they any decency, they would excuse themselves from the world of civil discourse.

The Agenda Project Action Fund sponsored a commercial in which a parade of prominent Republicans say, “Cut,” a word quite unsurprising within a political party that at least aspires to limited, lower-cost government. These clips are interspersed with frightful scenes of American medical personnel in hazmat suits responding to recent domestic Ebola cases. The most shocking images show Africans dying of Ebola, including one woman with blood streaming from her nose and down her cheek as she lies on the ground — either dead or terminally doomed.

Various graphics claim that the Centers for Disease Control’s discretionary budget was cut by $585 million since 2010. The National Institutes of Health budget supposedly was chopped by $446 million. Public Health Preparedness and Response: down $98 million. Infectious Disease Program: sliced by $13 million.

“Our budget has been slashed since 2003,” NIH executive Anthony Fauci says on Capitol Hill. “That was the left hook. The right cross was sequestration.”

“Republican cuts kill,” the spot concludes. “Vote.”

Also, the Democratic Congressional Campaign Committee posted an online ad claiming that “Republicans voted to cut CDC’s budget to fight Ebola.”

These anti-GOP attacks turn out to be humongous lies.

“This blame game earns Four Pinocchios” out of four, Washington Post fact checker Glenn Kessler wrote on Wednesday. This dubious distinction is reserved exclusively for the most mendacious public statements.

Writing for a newspaper well beyond the Vast Right-Wing Conspiracy, Kessler systematically dismantles the Left’s edifice of anti-Republican lies.

Regarding the CDC, Kessler notes that, “Before 2008, the agency received less than $6 billion a year.” However, “The numbers have bounced around $6.5 billion in recent years.” That is a budget increase, at least in nominal terms.

Moreover, Kessler adds: “In fiscal year 2013, the White House proposed a cut in CDC’s funding, but Congress added about $700 million. In 2014, the administration again proposed reducing the budget, but Congress boosted it to $6.9 billion.”

That’s right, folks. Obama tried twice to cut the CDC’s budget. But Congress — including the mean, horrible, sexist, and obviously racist Republican House of Representatives — reversed Obama’s budget cuts and increased spending on the CDC.

Data furnished to me by the House Appropriations Committee confirm Kessler’s refutation of this anti-Republican hate speech.

For Fiscal Year 2010, (the last year Democrats controlled Congress), Obama requested $6.7 billion for the CDC. Congress enacted $6.78 billion.

For FY 2014, Obama asked for $6.64 billion — fully $60 million less than he wanted in 2010. Obama unilaterally tried to cut CDC spending to levels below what he himself proposed four years ago. Still, Congress — including those vicious House Republicans — allocated $6.9 billion, a $260 million increase.

As for the NIH, Kessler reports, its budget rose “from about $28.5 billion in 2006 to $30.14 billion in 2014.” While it lagged inflation, this was at least a nominal budget hike that coincides with the tenure of today’s GOP House, in power since January 2011.

Once again, Obama attempted to cut medical-research spending, only to see a half-Republican Congress stop him in his tracks.

“In 2013, for instance,” Kessler explains, “Congress gave the NIH more than what the White House had requested, but then $1.5 billion was taken away by sequestration.”

Ah, sequestration.

This was the notorious conspiracy by heartless Republicans to shrivel the federal government “down to the size where we can drown it in the bathtub,” as Grover Norquist of Americans for Tax Reform loves to say, while twirling the tips of his handlebar moustache.

In fact, the sequester proved to be less about drowning Uncle Sam than sprinkling on him a drop or two of mild fiscal restraint. Reports of America’s post-sequester demise were obscenely exaggerated. But the sequester’s almost imperceptible spending reductions were too much for Congress. They vanished in January, due to Rep. Paul Ryan (R., Wisc.) and Senator Patty Murray’s (D., Wash.) bipartisan budget agreement.

In any case, the sequester was Obama’s idea.

“Obama personally approved of the plan for Lew and Nabors to propose the sequester to Senate Majority Leader Harry Reid,” the Washington Post’s Bob Woodward details in his book The Price of Politics, referring to then-budget director Jack Lew and Rob Nabors, Obama’s chief congressional-affairs aide. “Nabors has told others that they checked with the president before going to see Reid.”

“The president is part of the sequester,” then-Senate finance committee chairman Max Baucus said on February 20, 2013. “The White House recommended it, frankly.”

When, typically, Obama pointed fingers at Republicans for his own proposal, Obama earned himself yet another four Pinocchios.

What about the current budget?

“For fiscal year 2015, the [NIH fiscal] documents show, it was the Obama White House that proposed to cut the NIH’s budget from the previous year,” Kessler observes. “Moreover, we should note that President George W. Bush, a Republican, is responsible for significantly boosting NIH’s funding in the early years of his presidency.”

Here, too, the House Appropriations Committee’s observations mirror Kessler’s.

Congress spent $27.8 billion on the NIH in FY 2004. That rose to $29.9 billion in FY 2014 — a $2.13 billion hike.

Moreover, the NIH may shift as much as 1 percent of its budget into emergency needs. So, NIH Director Francis Collins could have spent up to $299 million on Ebola research this year, if he wanted.

The secretary of Health and Human Services also has limited discretionary spending authority. If she were not so busy in recent years inflicting ObamaCare on the American people, perhaps former HHS secretary Kathleen Sibelius could have dedicated some of her budget to cure Ebola.

With the Left’s carefully plotted assault on Republicans over Ebola now consumed by a five-alarm fire, Kessler hurled a few more buckets of gasoline atop this inferno.

Obama’s Republican predecessor oversaw big increases in public-health sector spending, and both Democrats and Republicans in recent years have broadly supported efforts to rein in federal spending. Sequestration resulted from a bipartisan agreement. In some years, Congress has allocated more money for NIH and CDC than the Obama administration requested. Meanwhile, contrary to the suggestion of the DCCC ad, there never was a specific vote on funding to prevent Ebola.

As columnist Michelle Malkin points out, the CDC has funneled taxpayer dollars into such vital disease-control initiatives as preventing playground injuries, promoting a federal motorcycle-helmet law, and pushing “anti-gun screeds, anti-smoking propaganda, anti-bullying lessons, gender inequity studies, and unlimited behavior modification programs that treat individual vices — personal lifestyle choices — as germs to be eradicated.”

Conservatives and liberals can debate how much federal research funding — if any — is the correct amount to degrade and destroy Ebola and other diseases. Such a conversation would be well served if it were disinfected of the despicable, partisan lies that the Left was caught spreading this week like a deadly virus.
