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:

* Reports out of Iowa suggest the state’s presidential caucuses will be held on Jan. 3, under “a tentative agreement that will be formally voted on around Oct. 16.”

* Republican officials are pressing New Hampshire Secretary of State Bill Gardner not to schedule the GOP presidential primary too early, with the goal of preventing Iowa of pushing its caucuses into December. A spokesman for Gardner said he has no plans to make a decision before next week.

* Mitt Romney’s campaign is being accused of pressuring Nevada Republicans to hold its presidential caucuses earlier than Republican National Committee rules allow. Aides to the former governor didn’t want to talk about it yesterday.

* Following Sen. Scott Brown’s (R-Mass.) inappropriate comments about Democratic challenger Elizabeth Warren yesterday, Brown turned to two of his female colleagues — Republican Sens. Kelly Ayotte (N.H.) and Susan Collins (Maine) — to not only defend him, but to suggest he’s a victim.

* Speaking of Massachusetts, one of Warren’s Democratic primary opponents, Bob Massie, has dropped out of the Senate race.

* President Obama’s popularity has dropped in North Carolina, but the latest survey from Public Policy Polling still shows him with small leads over Rick Perry and Mitt Romney.

* Herman Cain said yesterday he would consider running as his party’s vice presidential nominee, though he added, “Quite frankly, based upon Governor Perry’s position on some issues, I would not be comfortable being his vice presidential nominee.”

* President Obama has personally urged former U.S. Surgeon General Richard Carmona to run for the Senate in Arizona next year. The president also made clear he intends to heavily compete in Arizona next year, which he did not do in 2008.
