Back in 2008, Barack Obama’s campaign ran this commercial:

ANNCR: Barack Obama. Endorsed by Warren Buffett and Colin Powell.
And John McCain’s latest endorsement?
CHENEY: I’m delighted to support John McCain and . . .
CHENEY: I’m pleased that he’s chosen a running mate with executive talent, toughness and common sense, our next vice president Sarah Palin.
ANNCR: And boy did McCain earn it. He voted with Bush and Cheney 90% of the time.
CHENEY: I’m delighted to support John McCain.
ANNCR: And that’s not the change we need.
Approved by Barack Obama. Paid for by Obama for America.
OBAMA: I’m Barack Obama and I approved this message.

The campaign spent $5.1 million on that particular ad, showcasing the endorsement, in most of the battleground states, according to research by Evan L. Tracey, founder and president of Campaign Media Analysis Group, a TNS Media Intelligence company (and an invaluable resource).

What is famous Obama endorser Warren Buffett saying these days?

WARREN BUFFETT: We have a health system that, in terms of cost, is really out of control, and if you take this line and you project what has been happening into the future, we will get less and less competitive. So, we need something else. Unfortunately, we came up with a bill that really doesn’t attack the cost situation that much and we have to have a fundamental change. We have to have something that will end the constant increase in medical cost as a percentage of GDP.
BECKY QUICK: Then, are you in favor of scrapping this and going back to start over?
BUFFETT: I would be — if I were President Obama, I would just show this chart of what’s been happening and say this is the tape worm that’s eating at American competitiveness, and I would say that one way or another, we’re going to attack cost, cost, cost, just like they talk about jobs, jobs, jobs in the economy. It’s cost, cost, cost in this side.

If Warren Buffett’s opinion was important enough to spotlight in $5.1 million in campaign ads, why is he being ignored now?
