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.

* Paterson was out of friends and out of options: “Gov. David A. Paterson is set to announce that he will not seek election in the wake of reports that he and the State Police intervened in a domestic-assault case against a senior aide, according to a person told about the plans. He is expected to make the announcement this afternoon.”

* Scuttlebutt is getting louder that Florida Gov. Charlie Crist will leave the GOP and run for the Senate as an independent. The governor’s campaign described the rumors as “patently false.”

* In Illinois, a Research 2000 poll conducted for Daily Kos shows state Treasurer Alexi Giannoulias (D) leading Rep. Mark Kirk (R) in their Senate race, 43% to 36%.

* The same poll shows Illinois Gov. Pat Quinn (D) leading his Republican challengers by double digits, in Quinn’s bid for a full term.

* A Suffolk poll in Massachusetts shows incumbent Gov. Deval Patrick’s (D) support slipping statewide, though he still narrowly leads in a three-way contest. Patrick, who’s running for re-election this year, has 33% support, followed by Republican Charlie Baker with 25%, and state Treasurer Tim Cahill, a former Dem running as an independent, with 23%.

* In Nevada, a Mason-Dixon poll shows incumbent Gov. Jim Gibbons (R) still trailing in his primary race against Brian Sandoval (R), but the margin is a little closer. A month ago, Sandoval led by 16 points. Now, his lead is down to seven points.

* In North Carolina, where Sen. Richard Burr (R) is considered vulnerable, a new Rasmussen poll shows him with comfortable leads over his Democratic challengers.

* The race to replace the late Rep. John Murtha (D) in Pennsylvania is still in flux, with former Lt. Gov. Mark Singel (D) unexpectedly quitting yesterday. The leading Dems are now former state Treasurer Barbara Hafer and former Murtha aide Mark Critz.
