Only Huckabee has net positive favorability numbers, with 45% rating him favorably to 35% with an unfavorable opinion. Voters are quite negative toward Gingrich (31/50) and even Romney (32/44), allowing Obama to stay competitive with them despite his own poor numbers. And of course Palin's figures are the worst with 56% of voters expressing a negative opinion of her to only 37% with a positive one.
