Dear Rick Perry: It's time

Rick Perry’s campaign has come to an end. But he could leave on an unexpected high note — helping conservatives unite around one not-Romney in a way no one else has been able to. Rick Perry could be the catalyst and kingmaker so many have been looking for, even as other conservatives have stood by, unwilling to endorse in the face of long odds.

Rick Perry has come this far motivated by his faith and his principles. He has fought the good fight. He has not forgotten what is due to his own honor and that of his country. But now he has a choice to make, and I wish him wisdom in it.

Either Rick Perry will leave the race Sunday with no political capital and no deposit of goodwill an endorsement would bring, or he will choose to strike one final blow for limited government conservatism.
