Lieberman’s decision to endorse McCain now means—oddly enough—that he’ll face less criticism from Democrats than if he had waited. If Lieberman’s support for McCain is known it will have less impact in a general election if McCain is the Republican nominee. While if McCain misses out on the nomination and Lieberman returns to the Democratic fold it will be a newsworthy event.
The value of the endorsement for McCain is that it bolsters his chances with independents in New Hampshire whose support he desperately needs if he is to win in this do or die state for him. With both the big newspapers in New Hampshire endorsing him and Mitt Romney, the current New Hampshire frontrunner, expected to take a tumble in the Iowa Caucuses just five days before New Hampshire votes, McCain has a real chance to pull off a comeback victory in the Granite State.
