Chris Simcox the founder of the Minuteman Civil Defense Corps and a prominent figure in the movement to clamp down on illegal immigration, will announcing tomorrow at an event on the Mexican border that he's resigned from the group to run in the 2010 Senate primary.
From a forthcoming release:
"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. "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."
