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

* Now that Democrats have apparently hurt the feelings of the U.S. Chamber of Commerce, the business lobby vowed yesterday to “ramp up” its campaign activities.

* As triage rules the day, the Washington Post‘s Aaron Blake has a list of U.S. House races where Democrats have “canceled all of their ad reservations.” The silver lining? Dems are pulling back in two of the races because they’re confident of success.

* In Nevada’s U.S. Senate race, extremist candidate Sharron Angle (R) reportedly raised an astounding $14 million in the third quarter. Dems are skeptical about the claim, given that the Angle campaign hasn’t released its cash-on-hand numbers, so it’s hard to say how much of the $14 million has already been spent.

* On a related note, the latest survey of the race from Public Policy Polling shows Senate Majority Leader Harry Reid (D) leading Angle by just one point, 49% to 48%.

* In the state of Washington, a new Elway Poll shows incumbent Sen. Patty Murray (D) leading Dino Rossi (R) by a healthy margin, 51% to 38%. Mail-in balloting, however, makes polling in state a little tricky. (thanks to T.K. for the tip)

* In Wisconsin’s U.S. Senate race, many Dems keep waiting for the gap to narrow, but it’s not yet evident in the data. A new Reuters/Ipsos poll shows Sen. Russ Feingold (D) continuing to trail far-right challenger Ron Johnson (R), 51% to 44%.

* In Florida’s U.S. Senate race, a new Quinnipiac poll shows Marco Rubio (R) leading Gov. Charlie Crist (I), 44% to 30%, while PPP shows Rubio up by 11, 44% to 33%.

* On a related note, Crist is picking up some fairly high-profile endorsements this week, with California Gov. Arnold Schwarzenegger (R) announcing his support for Crist yesterday, and Robert F. Kennedy, Jr. endorsing the governor’s Senate campaign today.

* In Illinois’ U.S. Senate race, a new Southern Illinois University poll shows Alexi Giannoulias (D) and Rep. Mark Kirk (R) tied at 37% each.

* And in Alaska’s U.S. Senate race, a new survey from Public Policy Polling for Daily Kos shows extremist candidate Joe Miller (R) narrowly leading write-in Republican Lisa Murkowski, 35% to 33%. Democrat Scott McAdams is a competitive third with 26%.
