Chris Simcox, a founder of the anti-illegal immigrant Minutemen, announced that he will challenge Sen. John McCain in next year's GOP primary. Simcox will officially kick off his campaign tomorrow in Phoenix.
"John McCain has failed miserably in his duty to secure this nation's borders and protect the people of Arizona from the escalating violence and lawlessness," Simcox said in a statement. "He has fought real efforts over the years at every turn, opting to hold our nation's border security hostage to his amnesty schemes. Coupled with his votes for reckless bailout spending and big government solutions to our nation's problems, John McCain is out of touch with everyday Arizonans. Enough is enough."
First Arlen Specter in Pennsylvania... Now McCain in Arizona. Do GOP primary challenges from the right in blue or purple states actually strengthen the Republican Party's chances in 2010? Or do they weaken them?
