WEDNESDAY’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.

* In New York, NYC Mayor Michael Bloomberg (I) is set to endorse state Attorney General Andrew Cuomo (D) in this year’s gubernatorial race.

* At this point, Cuomo may need the boost — a new Quinnipiac poll shows the frontrunner leading by only six over Carl Paladino (R). The Republican nominee is likely getting a post-primary bump, despite his record of sending racist and bestiality emails, and a platform advocating prisons for welfare recipients where low-income Americans would be trained in, among other things, “personal hygiene.”

* First Lady Michelle Obama, dubbed “The Closer” in some Democratic circles, will be making a series of campaign appearances in mid-October, including stops in Wisconsin, Illinois, Colorado, Washington, and California.

* Alaska Sen. Lisa Murkowski (R), dipping into her considerable campaign coffers, has already launched a new ad campaign explaining her write-in re-election bid.

* Christine O’Donnell (R), the extremist Senate candidate in Delaware, chatted with Sean Hannity for nearly 20 minutes last night, but said she would no longer speak to national news outlets.

* In Pennsylvania, a new Quinnipiac poll shows former right-wing Rep. Pat Toomey (R) with a seven-point lead over Rep. Joe Sestak (D), 50% to 43%.

* Colorado gubernatorial hopeful Dan Maes (R) appears to be having trouble with his campaign finances. In his latest filings, the Republican nominee has raised only $14,462 this month, as compared to $120,468 for Tom Tancredo (I) and $218,388 for Democrat John Hickenlooper.

* In California’s gubernatorial race, the latest survey from Public Policy Polling shows Jerry Brown (D) leading Meg Whitman (R) by five, 47% to 42%.

* Speaking of PPP and gubernatorial races, the same outlet shows Rick Snyder (R) well ahead of Virg Bernero (D) in Michigan, 52% to 31%.

* And Tennessee’s gubernatorial race is even more one-sided, with a new Crawford Johnson and Northcott poll showing Bill Haslam (R) leading Mike McWherter (D), 55% to 24%
