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:
* Charles and David Koch are reportedly partial to Scott Walker's presidential campaign, but they are also prepared to give Jeb Bush a chance to "audition for the brothers' support."
* The fact that the GOP presidential field is already overflowing with candidates apparently isn't dissuading Ohio Gov. John Kasich (R), who launched a 527 group yesterday. The organization, called "New Day For America," will allow the governor to raise money for travel and related campaign-like expenses.
* Chris Christie was very likely counting on support from Joseph Kyrillos, who chaired the governor's 2009 campaign, but Kyrillos just made a $10,000 donation to Jeb Bush.
* For the third time in three weeks, a high-profile Florida Republican has decided to skip next year's U.S. Senate race. Yesterday, it was Rep. Tom Rooney (R-Fla.) who said he'd run for re-election, but not Marco Rubio's Senate seat.
* Jeb Bush, eager to bolster his foreign policy bona fides, will travel to Germany, Poland, and Estonia, in early June. It's probably not a coincidence that all three are NATO members.
* The Democratic primary in Pennsylvania's U.S. Senate race got a little more crowded last week when Allentown Mayor Ed Pawlowski (D) launched his campaign, joining former Rep. Joe Sestak. Incumbent Sen. Patrick Toomey (R) is seeking a second term next year.
* And in fundraising news, the Democratic Senatorial Campaign Committee narrowly outraised its Republican counterparts in March, $5.26 million to $4.88 million. Despite being in the minority, the DSCC has so far outraised the NRSC every month of 2015.
