Donald Trump Thinks Rick Perry Should Take ‘IQ Test’ Before Presidential Debate

“.@realDonaldTrump-ism not conservatism but a toxic mix of demagoguery and nonsense,” the former Texas governor tweets in response

Another day, another Donald Trump doozie.

The presidential candidate, who’s soared to No. 1 among Republican presidential candidates in the latest Fox News poll, attacked opponent Rick Perry’s intelligence on Twitter Thursday.

“.@GovernorPerry just gave a pollster quote on me. He doesn’t understand what the word demagoguery means,” Trump tweeted.

He followed up with a proposal: “.@GovernorPerry failed on the border. He should be forced to take an IQ test before being allowed to enter the GOP debate.”

Trump’s tirade against the former Texas governor came after Perry tweeted: .-ism not conservatism but a toxic mix of demagoguery and nonsense.”

Trump also tweeted his ire at Senator John McCain, who was the Republican nominee for president in 2008.

“The thousands of people that showed up for me in Phoenix were amazing Americans. called them “crazies” — must apologize!” he tweeted.

Trump then insulted McCain’s intelligence: “. should be defeated in the primaries. Graduated last in his class at Annapolis — dummy!”

The real estate mogul campaigned in New Hampshire Thursday.

Trump can self-fund his campaign, but Hillary Clinton and Jeb Bush are atop the money mountain. Watch the video.
