Today’s installment of campaign-related news items that won’t necessarily generate a post of their own, but may be of interest to political observers:

* Though the margin of his lead has slipped a bit, Rick Perry still leads the Republican presidential field in the new CNN/Opinion Research poll with 30% support. Mitt Romney is second with 22%.

* That same CNN poll, by the way, shows President Obama leading Romney by one point (49% to 48%) and ahead of Perry by five points (51% to 46%).

* Once again, officials close to New Jersey Gov. Chris Christie (R) are shooting down rumors about the governor’s alleged interest in the presidential race.

* Perry, using footage from a Democratic Super PAC, has begun going after Romney for flip-flopping on the Race to the Top policy.

* If Jon Huntsman doesn’t improve his standing in the polls in the next couple of weeks, he may be deemed ineligible for the next Republican presidential candidate debate, scheduled for Oct. 18 in Las Vegas.

* In Massachusetts, Elizabeth Warren’s Senate campaign got a boost this morning, picking up an endorsement from former Sen. Russ Feingold (D) of Wisconsin.

* Absentee/early-voting totals voting in West Virginia suggests Democrats have the early edge.

* In Kentucky, incumbent Gov. Steve Beshear (D) is feeling good enough about his re-election prospects in five weeks that he’s willing to skip gubernatorial debates.

* And it looks like Republicans will have to pick a new favorite Democrat: former NYC Mayor Ed Koch announced today he’s “now on board the Obama Reelection Express.”
