TUESDAY’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:

* While extremist Senate candidate Joe Miller (R) in Alaska has been reluctant to answer questions about his professional background, yesterday he finally reversed course. The Republican Senate hopeful told the Anchorage Daily News that he was disciplined for violating ethics rules as a public employee, and conceded that he has “many flaws.”

* On a related note, if you’re waiting for Lisa Murkowski or Scott McAdams to drop out in Alaska, it’s almost certainly not going to happen.

* In a bit of a shock, a new survey from Public Policy Polling shows Rep. Joe Sestak (D) edging ahead in Pennsylvania’s U.S. Senate race, leading former Rep. Pat Toomey (R), 46% to 45%. Reminder: this is only one poll, and no other outlets show Sestak ahead.

* In Florida’s U.S. Senate race, a new Suffolk University poll shows Marco Rubio (R) leading Gov. Charlie Crist (I), 39% to 31%. Rep. Kendrick Meek (D) is third with 22%.

* The same poll, meanwhile, shows Alex Sink (D) leading Rick Scott (R) in Florida’s gubernatorial race, 45% to 38%.

* In Missouri’s U.S. Senate race, which the Democratic establishment seems to have all but written off, a new survey from Public Policy Polling shows Robin Carnahan (D) trailing Rep. Roy Blunt (R) by just five points, 46% to 41%.

* In Ohio’s gubernatorial race, it appears John Kasich (R) is pulling away. A new Quinnipiac poll shows the former Fox News personality and Wall Street executive leading Gov. Ted Strickland (D), 51% to 41%.

* In Wisconsin’s gubernatorial race, a new Wisconsin Public Radio poll shows Scott Walker (R) continuing to lead Tom Barrett (D), 50% to 41%.

* In New York’s two U.S. Senate race, a new poll from the New York Times shows both Kirsten Gillibrand (D) and Chuck Schumer (D) with very large leads.

* And in Arizona, a PPP poll commissioned by Daily Kos shows Jon Hulburd (D) edging past Ben Quayle (R), 46% to 44%, in the race to succeed retiring Rep. John Shaddegg (R) in this conservative district.
