The national conventions are over. Labor Day is past. Now begins the final stretch, the 58-day sprint to the finish line. Here are some questions enquiring minds are asking:

Which party comes out of the two-week convention period with the most momentum?

Pignanelli: That rusty Oldsmobile beater that is the national GOP was crawling down the highway with no chance of catching up to the Democrats. But with an infusion of "Palin power" in the gas tank, there is a roar in the engine not heard for a long time, and Republicans have a new boost of speed. Yet and despite John McCain's admirable attempts to distance the party from the unpopular president, the GOP momentum will soon stall from the heavy burdens of President Bush (the guy never mentioned in the convention). "Palin mania" is a distraction in the media but Barack Obama's followers remain unfazed and continue in their trajectory. This election is a mirror of 1980: an unpopular administration, but voter unease with the charismatic challenger. As with 1980, this contest will be decided by performance in the debates. Indeed, the vice presidential debates could influence the final outcome.

Webb: Democrats had a good convention. They emerged unified and enthusiastic, led by a ticket of two Washington insiders. Republicans had a fantastic convention, especially considering the shaky start: the loss of the entire first day and the major distraction and initial uncertainty, even disarray, over the Sarah Palin selection. The Republicans had a good second day at the convention and an incredible third day. The Giuliani/Palin one-two convention punch was the most effective political performance I've seen in many years of watching politics. John McCain topped it off with a terrific speech Thursday night. So the GOP base is charged up, independent voters are taking notice, and the McCain-Palin ticket is going to peak at the right time.

To be sure, a lot of election is yet ahead, and things are going to quickly deteriorate into a frenzy of mean, nasty and incessant attack ads and vitriolic rhetoric, especially in the battleground states. But no one doubts now that the Republican ticket can handle the heat. The Democratic attack theme of "four more years of George Bush" will wither under McCain's resurgent reputation as a maverick and a running mate as far from good-old-boy, Washington-insider status as one can get.

Is McCain's choice of Palin and her convention performance a home run or a strikeout?
