He's certainly no Nixon but Nixon wasn't the first losing candidate to run again and win. He's just the latest. Thomas Jefferson, John Q Adams, Andrew Jackson, William Henry Harrison all did. Cleveland lost reelection but went on to beat his successor Harrison in a rematch.
If the economy falters in the second term of Obama, Romney has a stronger case. I doubt he'd run again but he shouldn't be counted out just because he lost.
He didn't look disheveled in that photo; his shirt just didn't look pressed.
You want Romney to run again????
