THURSDAY’S CAMPAIGN ROUND-UP…. Today’s installment of campaign-related news items that wouldn’t generate a post of their own, but may be of interest to political observers.

* Hoping to wrap the primary race up once and for all, Dick Cheney this morning threw his support to Marco Rubio in Florida’s Senate race. The former V.P. took plenty of not-so-subtle shots at Rubio’s Republican opponent and one-time frontrunner, Gov. Charlie Crist.

* On a related note, Rasmussen shows Rubio leading in a hypothetical, three-way match-up, with 37% support. Crist is second in the poll with 30%, and Rep. Kendrick Meek (D) is third with 22%.

* And while Florida’s Senate field may be poised to shrink on the GOP side, it may be poised to grow on the Democratic side. Billionaire real estate developer and financier Jeff Greene, listed by Forbes as one of the richest people in the world, is thinking about taking on Rep. Kendrick Meek in a Democratic primary.

* In California, the latest Rasmussen poll shows state AG Jerry Brown (D) out in front over Meg Whitman (R) in the gubernatorial race, 44% to 38%.

* The DSCC still has high hopes for former North Carolina state Sen. Cal Cunningham in his potential bid against Sen. Richard Burr (R), but Cunningham appears to be struggling to fill his campaign coffers with the donations he’ll need.

* On a related note, Ohio Secretary of State Jennifer Brunner, one of the two top Democratic candidates running for the Senate this year, is in even worse financial shape, and ended the first quarter with only $79,000 in the bank. Her primary opponent, Lt. Gov. Lee Fisher, has $1.8 million in cash on hand.

* And scandal-plagued Republican Sen. John Ensign (R) isn’t up for re-election until 2012, but like all senators, he’s expected to keep raising money for the next race. In the first quarter of 2010, the humiliated far-right lawmaker raised just $50 — no, that’s not a typo — which came from one guy.
