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:
* Marco Rubio, riding a wave of positive press, now leads the Republican presidential field in the new Quinnipiac poll with 15% support. Jeb Bush is a close second with 13%, followed by Scott Walker with 11%. Ted Cruz is fourth with 9%, followed by Rand Paul with 8%.
* In the same poll, Hillary Clinton leads each of her GOP rivals in hypothetical match-ups, though by much smaller margins than nearly all other national polling.
* Maryland's Democratic Senate primary is getting very crowded with several big-name candidates, including former Lt. Gov. Kathleen Kennedy Townsend, who launched her statewide campaign this morning.
* As Rachel noted on the show last night, former Hewlett-Packard CEO Carly Fiorina will kick off her Republican presidential campaign on May 4, the same day as Ben Carson's campaign announcement.
* As hard as this may be to believe, Donald Trump has reportedly signed a lease for a campaign office in New Hampshire, which will open a week from tomorrow.
* If you're eager to know what Louisiana Gov. Bobby Jindal (R) thinks about marriage equality, he wrote a New York Times op-ed today reminding everyone he's against it.
* And Ray-Ban was apparently displeased by the fact that Rand Paul's presidential campaign is selling "Rand-Ban" branded Wayfarer sunglasses on its website. The senator's aides agreed to stop making the product available.
