Republican presidential candidate Nikki Haley has been throwing harder punches at GOP frontrunner Donald Trump, days before her make-or-break New Hampshire primary on Tuesday. The former U.N. ambassador on Sunday took shots at Trump's mental acuity, his cozy relations with foreign dictators and his position as an establishment figure. Dedicating her talking points to Trump attacks is a marked shift from Haley, who before the Iowa caucuses had primarily gone after Florida Gov. The thing is, normal people aren't obsessed with Trump like you guys are," Haley said in the interview. "If you want to talk about Trump, if you really want to talk about Trump, why don't you go ask him if he's gonna get on a debate stage?"
