In a recent piece, Congressional Quarterly's Craig Crawford wrote:
At the very least this should contradict Crawford's unsupported claim that Giuliani's "star has faded," but it is also useful to look at a further breakdown of the numbers. Among self-described "white evangelical/born again Christians," Giuliani has a 66.3 rating, also the highest in the survey. That puts him ahead of Condoleezza Rice (64.4), President Bush (58.1), John McCain (57.1) and Newt Gingrich (47.8). Mitt Romney's rating among evangelicals/born again Christians was 46.4, but that figure is not reliable because 67 percent of respondents in this category didn't know how they felt about him.
Yes, the New Hampshire primary is a long way off, and yes, even
though evangelicals have positive feelings about Giuliani, that
doesn't mean they'd vote for him despite his social views. However,
here we have yet another data point demonstrating Giuliani's broad
appeal even among those who are supposed to be the most
antagonistic toward his candidacy. In spite of this, we are
supposed to believe that McCain is the clear frontrunner for the
nomination, and that his toughest rival is Romney, a one-term
governor who is unknown to most of the country. Perhaps I'm
mistaken in my belief that Giuliani will ultimately capture the
Republican nomination, but it stuns me that so many pundits are
still writing off his candidacy in the face of mounting empirical
evidence that he'll be a force to be reckoned with.
