Former GOP presidential nominee Mitt Romney called Donald Trump a phony, fraud and con artist … Then he challenged the Republican front-runner to respond to his uncivil attacks with civility.

The former failed GOP nominee attacked Donald Trump with venom of a thousand snakes. Who needs Democrats when you got a Republican establishment that would rather eat their own than give up power to a political outsider.

This afternoon Governor Sarah Palin responded to Mitt’s attacks.

“Trump’s favorables just rose again… Silly man.”

Here’s the full text:

Trump’s favorables just rose again, as did the veil you willingly wore while being used by the corrupt political establishment who can’t afford to lose their power in liberal D.C. Your speech was so silly and contradictory it confirmed the reasons Trump received tens of thousands more votes than you did in your own home state that you governed. Silly man. Could the establishment really not find anyone credible in their holier-than-thou movement to spew the deception you regurgitated today on tv?

Independent, commonsense conservative patriots: now it’s our time to ramp it up, to prove even more adamantly that our movement in this time for choosing is wisely chosen by those who know what’s at stake for America. The political establishment’s desperation is nailing its coffin – obviously a good thing – but we mustn’t let the Alinsky tactics used to destroy our We the People movement go unanswered. His shoulders are broad, but Donald Trump must not carry this on his own shoulders. Thankfully, Mitt’s anti-Republican Platform speech just strengthened our own. Americans’ shoulders just got bigger and broader. Way to go, Mitt.
