Something told him if he becomes a senator he’s set for life. His kids are set for life. His grand kids are set for life.
Give me a break. He's a fighter. He fought against the GOP establishment to not pass stupid bills like the sequestration with automatic defense cuts. He is fighting for his seat so he can continue bringing conservative Tea Party values to the Congress and not be replaced with a RINO or a weak-willed pushover.
He’s set anyway as a 6 term member of the House of Representatives.
