MONDAY’S CAMPAIGN ROUND-UP….Today’s installment of campaign-related news items that wouldn’t generate a post of their own, but may be of interest to political observers:

* A new USA Today/Gallup poll taken over the weekend shows McCain leading Obama among registered voters, 50% to 46%. Among those identified as likely voters, the lead is even bigger, 54% to 44%.

* Nate Silver has an analysis piece on post-convention polling in general.

* In responding to the new McCain ad, the Obama team used the “l” word: “Despite being discredited over and over again by numerous news organizations, the McCain campaign continues to repeat the lie that Sarah Palin stopped the Bridge to Nowhere.”

* Obama and Bill Clinton will meet on Thursday at Clinton’s offices in Harlem. The New York Times said this will be their “first extended face-to-face encounter after more than a year of tense relations, aides said Sunday.”

* Speaking of the Clintons, Hillary Clinton will campaign for Obama today in Florida, with a discussion on the economy near Orlando this afternoon and a rally this evening in Tampa.

* Dick Cheney offers enthusiastic support for Sarah Palin. Condoleezza Rice’s support sounds more restrained.

* Joe Biden told Tom Brokaw yesterday that, as a religious matter, he believes life begins at conception. Biden is, however, pro-choice as a matter of government policy.

* The National Republican Senatorial Committee must feel pretty certain about Tom Udall’s (D) chances of winning the open Senate seat in New Mexico this year — the NRSC is calling off scheduled TV ads in the state.
