TUESDAY’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:

* The latest round of national polls show McCain’s lead over Obama somewhere between zero and two points.

* Obama campaign manager David Plouffe continues to insist the national polls are of little interest at this stage. “In this building we don’t spend a lot of time on national polls, we are very focused on the battleground states that will decide the race,” Plouffe told reporters. “We think McCain is more at his high water mark then we are.”

* Public Policy Polling shows Obama leading McCain in Michigan by one point, 47% to 46%.

* Rasmussen released a bunch of state polls yesterday. Obama leads in Colorado (+3) and Pennsylvania (+2), while McCain leads in Ohio (+7) and Virginia (+2). Rasmussen shows Obama and McCain tied in Florida.

* Sarah Palin has a group of close friends, who jokingly call themselves the “elite six,” and who got to know each other through aerobics classes. Three of the six, though, aren’t sure if they’re even willing to vote for her.

* If ABC News’ Charlie Gibson wants to ask Palin some good questions, the Anchorage Daily News has some very helpful suggestions.

* It looks like Georgia is off the Obama campaign’s wish list.

* Last week, Heart demanded that the McCain campaign stop playing “Barracuda” at its events. The campaign, which claims to have paid for and obtained all necessary licenses, is apparently playing the song anyway.
