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:

* Rep. Gabrielle Giffords (D-Ariz.), a year after surviving an assassination attempt, has decided she’ll step down from Congress this week to focus on her ongoing recovery. Giffords will not seek re-election in November.

* On a related note, Gov. Jan Brewer (R) will have to set a day for a special election, and Democratic officials hope to persuade Giffords’ husband, astronaut Mark Kelly, to run for the seat.

* There were rumors Saturday night that former Florida Gov. Jeb Bush (R) would make an endorsement in the Republican presidential race, but he said yesterday he will “stay neutral” until after next week’s primary.

* Speaking of Florida, some initial polling suggests Newt Gingrich received a post-South Carolina bump in the polls.

* And speaking of Gingrich, the disgraced former House Speaker’s campaign reportedly pulled in more than $1 million since his win on Saturday night.

* Sen. Orrin Hatch’s (R) odds of re-election in Utah have improved, but the right-wing FreedomWorks organization still hopes to derail his campaign in advance of the state Republican Party’s convention.

* New Jersey Gov. Chris Christie (R) has once again said he’s open to running as Romney’s running mate, though yesterday he said he’s “inclined” to stay in his current job.

* Former Republican National Committee Chairman Michael Steele conceded on Friday that he believes it may be “very, very hard” for his party to maintain a House majority after the 2012 elections. He added that Republicans are “going to have to come with a good A game to hold it.”
