FRIDAY’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 Obama campaign released to the public this morning 10 years of tax returns from Joe Biden and his wife. Expect to see Sarah Palin pressured to be equally forthcoming.

* Palin’s first cable interview will be with Sean Hannity. Shameless.

* Bill Clinton and Barack Obama had lunch together at the former president’s Harlem office yesterday. Talking briefly with reporters, Clinton was asked for his opinion on the state of the race. “I predict that Sen. Obama will win and win handily,” Clinton said. Obama added, “There you go. You can take it from the President of the United States. He knows a little something about politics.”

* The McCain campaign unveiled an strikingly pathetic television ad this morning, accusing the Obama campaign of being “disrespectful” and “lying” about Sarah Palin. called the ad “particularly egregious,” and said McCain is pursuing “new paths of deception.”

* The same ad violated the agreed upon 9/11 truce. Dishonest and dishonorable are not a good combination.

* The latest national poll from Ipsos/McClatchy shows McCain leading Obama by one, 46% to 45%. The same poll showed Nader third with 2% and Bob Barr fourth with 1%.

* Public Policy Polling shows Obama leading McCain in Colorado by one, 48% to 47%.

* Rasmussen shows Obama leading McCain in Washington state by two, 49% to 47%.

* Rasmussen shows Obama leading McCain in Michigan by five, 51% to 46%.

* Rasmussen shows McCain leading Obama in Wyoming by 19, 58% to 39%.

* The Defenders of Wildlife Action Fund has a brutal new ad, criticizing Palin’s support for hunting bear and wolves from airplanes.
