Bush stands at 19%, up from 13% in May — and his best showing in CNN/ORC polling since December. Trump follows at 12%, up from 3% before his announcement. Former Arkansas Gov. Mike Huckabee (8%), neurosurgeon Ben Carson (7%) and Kentucky Sen. Rand Paul (7%) round out the top five.
Notably absent from this top five — though statistically speaking not far behind — are Florida Sen. Marco Rubio (6%, down from 14% in May) and Wisconsin Gov. Scott Walker (6%, down slightly from 10%). Both had been top five candidates in each of the last two CNN/ORC polls, and Walker had been in the top five since February.
The poll, conducted just before New Jersey Gov. Chris Christie formally launched his campaign with a rally in Livingston, New Jersey, on Tuesday, also finds that Christie begins his push for the presidency with just 3% support.
The findings suggest Bush is making progress toward being seen as the frontrunner in a field that has long lacked a clear leader.
