Independents are actually less likely to support escalation if it is framed as McCain doctrine than they are if it is framed as President Bush’s. They are the only partisan group to do so. Even Democrats are slightly more likely to support the increase in troops if it is listed as McCain’s plan than they are if it is listed as Bush’s. … In case you needed confirmation that the number of Independents supporting John McCain is decreasing rapidly, this may be it.

Well, maybe. I am sympathetic to the view that McCain will not command the kind of support from Indies that he enjoyed in 2000, but the margins are not wide enough to warrant such a conclusion, and the commenters seem to agree. But as we’ll see below, there is another story to be interpreted from this question, one which confounds my own expectations.

Below I have reproduced the charts Singer relied upon, with the sole difference being that I have Turnerized the table frames we’ll be discussing:

Do you favor or oppose President Bush’s proposed strategy of increasing the number of American troops in Iraq by as many as 20,000 troops over then next few months?

If we combine the strongly/somewhats across the board and account for the opinion-deficient, we find Republicans supporting Bush on the issue 57-35-8, whereas Independents oppose his plan 35-61-4. For McCain, the same question yields 66-27-10 Republican support and 30-49-20 opposition from Independents. The numbers themselves should be taken with a grain of salt, but the patterns are notable.

First of all, the poll confirms others showing that the surge is unpopular, and even among Republicans support is lukewarm. Another conclusion from the above tables is relatively unsurprising: Republicans support Bush more than Independents do.

Putting aside Singer’s point for the moment, there is one more conclusion left unaddressed: Republicans support the surge when associated with McCain over Bush — and by a 9-point margin.

That’s good news for McCain, for whom the big question has been whether he can actually win the nomination; Independents are supposed to be his natural constituency, while he is weak with registered Republicans. But Republican angst about Iraq is on the rise, and the rank-and-file will be looking for the candidate most able to reassert leadership on the war — and on this issue, he actually bests the Republican commander-in-chief. That sure can’t be bad news. However, it would be nice to see how McCain stacks up against the other Republicans. Alas, Romney is the only one tested (fav/unfav only) and across the board, 49% of everyone has never heard of him.

Singer’s conclusion is correct on the face of it: Independents support Bush more than McCain, or more appropriately, oppose him less. But his readers correctly note that while Indies know they don’t like Bush on Iraq, a statistically significant 20% have no particular opinion on the issue vs-à-vis McCain. That could mean they’re on the fence now, but are open to being persuaded by McCain.

Or maybe that McCain Googlebomb just needs a little more time?
