MONDAY’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.

* Club for Growth Chairman Pat Toomey stepped down from his position this morning, almost certainly in advance of a Senate campaign against Sen. Arlen Specter (R) of Pennsylvania.

* In New York’s 20th, Democrat Scott Murphy now leads Republican Jim Tedisco by 35 votes.

* New York City Michael Bloomberg has worked to gain multiple ballot slots as he seeks a third term, and has been largely successful. Bloomberg will be the Republican nominee, despite having left the GOP in 2007. He will also be the Independence Party nominee.

* Is Sen. Richard Burr (R) vulnerable in his re-election prospects in North Carolina next year? It sure looks like it.

* Texas Gov. Rick Perry (R) must be pretty worried about next year’s Republican primary.

* There’s apparently some kind of rule requiring every likely presidential candidate to write a book, and apparently, Louisiana Gov. Bobby Jindal (R) is sticking to the rules.

* On a related note, it’s one of those rumors I find very hard to believe, but New York magazine’s John Heilemann said over the weekend that Jindal is thinking about running against Sen. David Vitter (R) next year*. Don’t count on it.

* corrected
