In his latest National Journal column, political oracle Charlie Cook remains bullish on the Republicans’ chances in November. Beginning with the latest NBC News/Wall Street Journal, Cook paints a bleak picture for the Democrats:

Among the registered voters in the survey, Republicans led by 2 points on the generic congressional ballot test, 45 percent to 43 percent. This may not sound like a lot, given that Democrats now hold 59 percent of House seats. When this same poll was taken in June 2008, however, Democrats led by 19 points, 52 percent to 33 percent. That drop-off should be enough to sober Democrats up, but the next set of data was even more chilling. First, keep in mind that all registered voters don’t vote even in presidential years, and that in midterm elections the turnout is about one-third less. In an attempt to ascertain who really is most likely to vote, pollsters asked registered voters, on a scale of 1 to 10, how interested they were in the November elections. Those who said either 9 or 10 added up to just over half of the registered voters, coming in at 51 percent.
Hart and McInturff then looked at the change among the most-interested voters from the same survey in 2008. Although 2010 is a “down-shifting” election, from a high-turnout presidential year to a lower-turnout midterm year, one group was more interested in November than it was in 2008: those who had voted for Republican John McCain for president. And the groups that showed the largest decline in interest? Those who voted for Barack Obama — liberals, African-Americans, self-described Democrats, moderates, those living in either the Northeast or West, and younger voters 18 to 34 years of age. These are the “Holy Mackerel” numbers.

Things could still change, Cook warns, if the Republicans’ failure to turn out impressive numbers in the May special elections is to be repeated. “But,” he says. “[T]he recent numbers confirm that trends first spotted late last summer have fully developed into at least a Category 3 or 4 hurricane.”
