"Certainly both Reagan and Pat Buchanan were running from the right, so this would be something new, and it won't go very far," Bowman, a senior fellow at the American Enterprise Institute, told Hill.TV's Jamal Simmons on "What America's Thinking." 

Before he was president, Ronald Reagan challenged then-President Gerald Ford in the 1976 Republican primary, while Pat Buchanan challenged then-President George H.W. Bush in the 1992 Republican primary. 

"If you challenge an incumbent president, you have to deal with a lot of enthusiasm, a lot of mobilization," Marist Poll director Lee Mirinigoff said in the same segment. "That's not the middle."
