Perhaps Mitt Romney's greatest vulnerability is the sense many voters and journalists have of him that his values are situational, that he'll take one position on an issue when it helps him politically and the opposite stance when that's advantageous.

GOP White House hopefuls debate in New Hampshire. Tim Pawlenty seems to back off his "Obamneycare" comment. Newt Gingrich's senior staff decamps, many head to Rick Perry's corner. Plus: Rep. Weiner takes the hint and resigns. Obama and House Speaker John Boehner to talk budget between bogeys.
