Jeb Bush is trying to jump-start his campaign this week, with a new focus and a new slogan: "Jeb Can Fix It."
That's meant to highlight his two terms as governor of Florida, but it might also apply to his lackluster campaign.
Bush's hopes to dominate the race as front-runner are a distant memory, with outsider candidates like Donald Trump and Ben Carson leading the field since the summer.
But lately, Bush has been fighting more fiercely with a man he once mentored, Marco Rubio. When Bush was governor, Rubio served as speaker of the Florida House of Representatives.
