PPP Poll: Walker leads with GOP conservatives, Bush leads with moderates

Scott Walker is the darling of GOP conservatives, which is why he's leading the Republican field at 17 percent, according to a new PPP poll. Trailing close behind is Jeb! at 15 percent, Marco Rubio at 13 percent, Ben Carson with 12 percent, Mike Huckabee at 11 percent, and Ted Cruz and Rand Paul both at 8 percent.

Walker continues to lead thanks largely due to his strength with voters who identify themselves as 'very conservative.' Among them he gets 23% with Carson at 17%, Cruz at 13%, and Huckabee at 11%, the other candidates who enter double digits.

Hmm. Who's missing from that list? Oh yeah—Jeb! Jeb's lack of popularity among conservatives accounts for a lot, including his negative favorability ratings and his second place status (though he did gain four points since last month's poll).

He actually starts out with a negative favorability rating among GOP primary voters- only 37% see him favorably to 40% with an unfavorable view. That's largely due to his struggles with conservatives- just 32% of 'very conservative' primary voters have a positive opinion of him while 51% see him negatively. Bush does lead the field with moderates at 19% to 17% for Rubio, 15% for Paul, and 10% for Huckabee.

Rubio claims the highest favorability rating at 59 percent, with only 16 percent of Republicans having a negative view of him.
