Erick Erickson: I Will Never Vote for Trump

"I will not rally to Trump."

Even as presidential candidate Donald Trump racks up caucus victories, the polarizing frontrunner elicits some very vocal opposition from within Republican ranks as well.

Erick Erickson of RedState, for example, has formally vowed he will not be voting for Donald Trump, even if he becomes the Republican nominee for president. 

Erickson based his decision primarily on Donald Trump's stance on abortion, saying the real-estate mogul never truly flipped his views, and only says so for convenience. 

"I have become convinced that Donald Trump’s pro-life conversion is a conversion of convenience," he wrote in a post on his website, The Resurgent. "Life is the foremost cause in how I vote. Therefore I will not be voting for Donald Trump at all. Ever."

Though Erickson previously stated he would support Trump if he became the nominee, he now states his mind has changed:

"If Trump were elected President, there would be members of the pro-life movement who would compromise their convictions for access to power. If Trump were elected, portions of the conservative movement would compromise the movement to be one degree from Donald Trump. The intellectual institutions on which we have made our case for limited government and freedom would crumble."

To defeat Trump, according to Erickson, conservatives now have a duty to rally in support of Marco Rubio:

"I will not rally to Trump. Frankly, if Trump is able to get the nomination, the Republican Party will cease to be the party in which I served as an elected official," Erickson said in Monday's post. "It will not deserve my support and will not get it if it chooses to nominate a pro-abortion liberal masquerading as a conservative, who preys on nationalistic, tribal tendencies and has an army of white supremacists online as his loudest cheerleaders."
