It used to be that Indiana state Sen. Greg Walker was the one poaching big game inside the GOP. 

In 2006, he bagged the biggest “RINO” possible, taking out the long-serving state Senate leader, Bob Garton. Walker toured the state Senate district centered on Columbus, Indiana, in a refurbished orange 1970 Slant-6 Plymouth Valiant, encouraging supporters to scrawl in permanent marker on the campaign sedan.
