Marco Rubio continues to lead nationally, as he has on all four of our 2016 polls so far. He's at 21% this month, basically the same as 22% the month before the State of the Union address. Rubio's favorability of 62/10 is slightly better than 59/12 in early February. The whole water drinking episode hasn't had any effect on his standing- nor has his stance on immigration reform.
The big move though has come from Paul. In early February he was in 6th place among Republican contenders at just 10%. Now he's vaulted all the way up to 2nd place at 17%. Chris Christie is 3rd at 15% and Paul Ryan and Jeb Bush are tied for 4th at 12%. Rounding out the folks we polled are Rick Santorum at 5%, Bobby Jindal at 4%, Rick Perry at 2%, and Susana Martinez at 1%.
