The Manchester Union-Leader has endorsed Newt Gingrich, which pretty firmly establishes the former speaker as the chief "not-Romney" candidate.
Either man is an infinite improvement over the current occupant of The White House, but there is plenty about which the GOP electorate should be informed before following the Union-Leader's advice to vote for Gingrich.
No, politics shouldn't become the exclusive province of "the rich" -- and yes, I am aware that Mitt Romney is quite rich. All that said, it's worth noting that he earned most of his wealth himself, through the private sector, and entered politics after making a name for himself elsewhere.
