New PPP polls
both nationally and in Iowa find Marco Rubio and Hillary Clinton leading the way for their party's respective 2016 nominations, with Clinton leading Rubio by 8 points in a hypothetical head to head. For the third month in a row in our national 2016 GOP tracking Rubio leads the way. He's at 22% to 15% for Paul Ryan, 13% each for Jeb Bush and Chris Christie, 11% for Mike Huckabee, 10% for Rand Paul, 4% for Bobby Jindal, 3% for Rick Perry, and 1% for Susana Martinez. Rubio continues to lead based on his appeal to the furthest right segment of the Republican Party- he's at 28% with 'very conservative' voters to 15% for Huckabee and 14% for Ryan.
Rubio's tied for the lead in Iowa as well. It's a closely contested picture there with he and Huckabee both at 16%, followed by Paul at 15%, Bush at 14%, Christie at 12%, Ryan at 10%, Martinez at 4%, and Jindal and Perry at 3%. Rubio leads with conservatives there.
