“I think John Kasich would be the best nominee, but he doesn't have a chance,” Graham said during an appearance Thursday on MSNBC's "Morning Joe." 

“John Kasich's problem is he is an insider in an outsider year and nobody seems to want to buy that,” he added.  

Graham signaled his support for Cruz last week, when news emerged he would be hosting a fundraiser for him. This comes after harsh comments Graham made about his Senate colleague, including while running against the Texas senator in his own White house bid.
Graham has argued that while he has differences with Cruz (joking the runner-up in delegates was his "15th choice" in the race), he's the best-positioned Republican other than Donald TrumpDonald John TrumpSarah Huckabee Sanders becomes Fox News contributor The US-Iranian scuffle over a ship is a sideshow to events in the Gulf South Korea: US, North Korea to resume nuclear talks 'soon' MORE.

"I think he'd make a better president than Trump for damn sure, and I think he'd take the country in a new direction other than Clinton," Graham said. 

Asked if Kasich would make a better president than Cruz, Graham said, "I think so." 

He called Trump a "con man" and blasted the GOP front-runner for his support of waterboarding in the wake of this week's terrorist attacks in Brussels. 
"I have differences with Ted Cruz that are well known, but I think we share the same political DNA and at the end of the day I think he's a reliable Republican conservative and Mr. Trump is not," Graham said.

"I'm not going to stand behind a guy that gets David Duke's support," Graham said of Trump. "So it's no longer about winning the election for me, it's trying to salvage a party that I love and conservatism as I know it."
