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:
* Will Sen. Rand Paul (R) be able to run for re-election in Kentucky while also running for the Republican presidential nomination? It sure looks like it.
* Appearing at an Iowa agricultural event over the weekend, former Gov. Jeb Bush (R) endorsed phasing out federal resources for renewable fuels and wind energy. That's not even close to what Iowa's political and industry leaders wanted to hear.
* On a related note, the Iowa Ag Summit was supposed to be non-partisan, but "organizers turned away some ticket-holders who were registered Democrats without explanation."
* After struggling badly on foreign policy in recent weeks, Wisconsin Gov. Scott Walker (R) is receiving training and a "crash course" on international affairs from "some of the GOP's leading foreign-policy lights."
* In the new NBC News/Wall Street Journal poll, 42% of Republican primary voters say they couldn't support Jeb Bush's presidential campaign. The news was slightly worse for Chris Christie: 57% of GOP primary voters say they couldn't support him.
* In the latest McClatchy-Marist poll, Hillary Clinton leads each of her likely Republican rivals in hypothetical 2016 match-ups. Margins range from 4 points (against Walker) to 14 points (against Ted Cruz).
* I'm not surprised Senate Minority Leader Harry Reid (D-Nev.) has thrown his support to Rep. Chris Van Hollen's (D-Md.) Senate campaign in Maryland, but I'm a little surprised Reid weighed in so early in the process.
* On a related note, Rep. Donna Edwards (D-Md.) is also set to launch her campaign, setting up an epic primary fight with Van Hollen.
* And believe it or not, Sen. Lindsey Graham (R-S.C.), a likely 2016 presidential candidate, has never sent an email to anyone. "I don't email," Graham told NBC's Chuck Todd yesterday. "You can have every email I've ever sent. I've never sent one."
