I am not a big fan of polls, but one of our fans reminded us that we should keep them in mind, so Gallup Daily: McCain Moves Ahead, 48% to 45%. Rasmussen has it 48-48. Real Clear Politics has details of a bunch of polls, and an average of Obama up by .8.
Update: This is why I don't like polls--they are constantly frickin' changing. This morning, the Real Clear Politics average has McCain up by 1.2 (same link as above), largely on the strength of a no doubt overblown 54-44 lead in a USA Today/Gallup poll of likely voters.
To the extent that these polls mean anything, and to point out the obvious, it that Senator McCain and Governor Palin had a very good convention. But why they had a good covention is the question. Lots of folks are focused on Palin's speech and her conservatism, for good reason. But my feeling is that McCain's big tentiness played better than most realized, and to the degree that the current polling numbers hold up (and they will change, damn them) it will be because of that.
