Marco Rubio Pulls Senators Off Bush Bandwagon

Faced with sinking poll numbers and widely criticized debate performances, Bush and his campaign have attempted to engineer a turnaround tour, positioning the candidate as the most serious and well-informed on the extensive Republican slate. But he has struggled to shore up his conservative bona fides among GOP voters who see him as a compromised member of the establishment. Bush, who has seen his support slide almost uninterruptedly since July, has fallen to less than 6 percent, which has him in fifth place behind the front-runners, businessman Donald Trump and retired neurosurgeon Ben Carson, Rubio and U.S. Sen. Ted Cruz of Texas.
