Washington (CNN) Donald Trump has hit a new high in the race for the Republican nomination, according to a new CNN/ORC Poll, with more than 4-in-10 Republican voters nationwide now saying they back the billionaire. And more than two-thirds of Republicans say he's the candidate most likely to capture their party's presidential nomination. Trump has topped the 40% mark for the first time in CNN/ORC polling, standing at 41%. That more than doubles the support of his nearest competitor, Texas Sen. Ted Cruz, who notches 19% support in the poll. No other candidate hit double-digits. Florida Sen. Marco Rubio landed at 8%, retired neurosurgeon Ben Carson at 6%, former Florida Gov. Jeb Bush at 5%, New Jersey Gov. Chris Christie at 4%, and the rest at 3% or less.Trump tops 40% mark among Republican voters for the first time in CNN/ORC pollingMore than two-thirds say Trump is most likely to capture the nomination
