Pick your poll preference.

If you’re a Romney backer, you like Rasmussen:

Romney 29, McCain 27, Huckabee 19.

If you’re a McCain fan, you like Gallup:

McCain 32, Romney 21, Huckabee 18.

Pollsters try their hardest to get the best reading possible, but I think it’s easier to get a more accurate sense of where things stand in a state, with a voter pool of usually less than 2 million or so, than they do across the country, with a pool of tens of millions of voters.

UPDATE: Rasmussen’s newest tracking poll: McCain 30, Romney 28.
