In one fell swoop McCain will gain street cred with the staunch conservatives in the Republican party, making him far more palatable to them. It also gives him something else:
Behind the scenes, Vice President Thompson offers President McCain private counsel, guided by our Founding Fathers, without drawing attention to himself. Mr. Thompson seems eminently qualified for such a role, eschewing publicity and advancing the cause which impelled him to mount his own White House bid.
It works for me.
