So here’s a puzzle. If Rudolph W. Giuliani is leading the Republican field in the national polls, and Mitt Romney is leading the field in the early states, why is John McCain running closer to Hillary Clinton than the rest of the pack?
All the Republicans would lose to Mrs. Clinton if the election were held today, according to the ongoing poll analysis by realclearpolitics.com. But Mr. McCain does better than anyone against her in the hypothetical one-on-one match-ups.
He loses to her by 3.3 points. Mr. Giuliani is very close — he would lose by 4 points, which is insignificant but enough for Mr. McCain to claim bragging rights. Mr. Romney would lose to Mrs. Clinton by 10.3 points. Fred Thompson would lose by 11.7 points.
And yet in national polls, Mr. McCain is basically tied for third with Mr. Romney, trailing Mr. Giuliani and Mr. Thompson.
What accounts for this? What advantages does Mr. McCain bring against Mrs. Clinton that he doesn’t bring in match-ups against his rivals?
