The son of one the most revered of recent Republican presidents claims his father would have been appalled at the insurgent campaign of GOP front runner Donald Trump.

In in an interview with NewsMax, radio host Michael Reagan expressed his distaste for the scorched earth campaign the billionaire businessman is running against his Republican rivals, invoking his father, President Ronald Reagan, who was notable for his belief in the '11th Commandment' : "Thou shalt not speak ill of any fellow Republican."

"What he's done is really appalling," Reagan said. "My father would be appalled. … On behalf of my father and the Reagan family to see someone like this who just personally attacks people time and time and time again is absolutely appalling to me and I hope all the voters start to see through Donald Trump and the kind of candidate that he his and the kind of president he may end up being."

According to Reagan, Trump's campaign is long on inflammatory rhetoric and short on specifics.

"It's nice to say, 'I'm going to make America great again,' but how are you going to do that? What laws are you going to pass? What bills are you going to pass? How are you going to work with Congress? What are you going to do?" Reagan said.

Reagan was equally creeped out by the Trump's rabid followers, saying they could either be Reagan Republicans or Trump Republicans -- but not both.
