John McCain endorses Mitt Romney for President. Isn't that the same John McCain who endorsed Sarah Palin 4 years ago?

John, your judgment is of, well, to be honest, zero value. You proved 4 years ago that your ego and desire to win at any cost let you pick Palin as a running mate, disregarding the best interests of the country. Nice call then, why should anyone think your endorsement of Romney had any more merit. Hell, most rational people would look at your endorsement as a negative.
