For anyone who enjoys a) charts and b) speculating about who will win the Republican presidential primary in 2012, has just greatly improved your life: the site is now tracking favorability ratings for Mitt Romney and Mike Huckabee, as well as Sarah Palin. So, now that these charts exist, we may as well take a look at them.

More people view Sarah Palin unfavorably than favorably; Mike Huckabee is relatively constant; and Mitt Romney has somehow taken a downturn on both fronts. These polls measure overall favorability--not favorability among Republicans--so, less than the likelihood of a primary win, they measure how seriously any of these Republicans could challenge President Obama...and none of them are in his ballpark at the moment.
