Bloomberg was at one time a Republican. Powell still is but both supports Obama. What does that tell you? Moderate Republicans are leaving the party because of its far right agenda which does not represent the majority of the population. After having voted for Eisenhower, Nixon, Goldwater, and Ford I find that Republican party of today no longer reflects my views.
Christie did not endorse Obama for the presidency. He thanked him for addressing the catastrophe so promptly.As for endorsements I know no one who has voted solely on an endorsement. Do you?? If you can't make that important a decision on your own,maybe you shouldn't be voting.
