Struggling Republican presidential candidate Jeb Bush was forced to politely ask a group of supporters to applaud for him on Wednesday after a rant about his ability to lead the country was met with complete silence.Speaking at an event in Manchester, New Hampshire on Wednesday, Bush lashed out at GOP hopeful Donald Trump, and promised not to be a divisive president."My pledge to you, I will be a commander-in-chief that will have the back of the military," he said. "I won't trash talk, I won't be a divider-in-chief or an agitator-in-chief. I won't be out there blowharding, talking a big game without backing it up.""I think the next president needs to be a lot quieter, but send a signal that we're prepared to act in the national security interest of this country," Bush added. "To get back in the business of creating a more peaceful world."Bush paused, waiting for approval from the crowd. But instead, he was met with an awkward silence."Please clap," the candidate said, looking demoralized.The crowd obliged.
