Poll: Walker, Clinton lead in Iowa

PPP reports:

PPP's newest Iowa poll finds Scott Walker well ahead of the rest of the Republican field in Iowa, getting 23% to 13% for Marco Rubio, 12% for Jeb Bush, 10% each for Mike Huckabee and Rand Paul, 8% for Ted Cruz, 7% for Ben Carson, 5% for Chris Christie, and 4% for Rick Perry.

Walker has the highest favorability out of anyone in the field, with 59% of voters viewing him favorably to 13% who have an unfavorable view. The key to Walker's success is that he's winning both among voters who are most concerned about electability in the general election and among voters who are most concerned with having the most conservative candidate. Among voters who say being able to win in the general is their top priority, Walker gets 21% to edge out Marco Rubio (20%) and Jeb Bush (17%). His lead is much more emphatic among voters saying conservatism is their top priority- with them he gets 29% to 14% for Cruz, 12% for Paul, and 10% for Huckabee.

Rubio's second place standing reflects his recent rise nationally. Boding well for him is that beyond being in second place overall, he is also tied with Walker for being the most frequent second choice of voters at 13%. That gives him a lot of room to grow if other candidates falter along the way.
