Walker leads nationally in new poll

PPP reports:

PPP's newest national Republican poll continues to find a bunched up race at the top. Scott Walker leads with 17% to 15% for Jeb Bush, 13% for Marco Rubio, 12% for Ben Carson, 11% for Mike Huckabee, 8% for Ted Cruz and Rand Paul, 5% for Carly Fiorina, and 4% for Chris Christie. Small though the lead may be, this is the fourth consecutive national survey we've done where we found Walker out in front.

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.
