MONDAY’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:

* It seems inexplicable under the circumstances, but the U.S. Senate race may be slipping away from Democrats in Illinois. A new Chicago Tribune/WGN poll shows Rep. Mark Kirk (R) leading Alexi Giannoulias (D), 44% to 41%, despite Giannoulias’ earlier lead in the same poll. The latest Mason-Dixon poll shows Kirk ahead by a similar margin, 43% to 41%.

* In Florida, a new St. Petersburg Times/Miami Herald/Bay News 9 poll shows the state’s U.S. Senate race all but over, with Marco Rubio (R) leading Gov. Charlie Crist (I), 41% to 26%, with Rep. Kendrick Meek (D) third with 20%. The same poll shows Rick Scott (R) with a narrow lead over Alex Sink (D) in Florida’s gubernatorial race, 44% to 41%.

* In Colorado, a Denver Post/9 News poll shows the U.S. Senate race all tied up, with Sen. Michael Bennet (D) and Ken Buck (R) with 47% each. The same poll shows Denver Mayor John Hickenlooper (D) leading the gubernatorial race with 49% support, followed by former Rep. Tom Tancredo (I) with 39%, and Republican candidate Dan Maes with 9%.

* In California, a Los Angeles Times/USC poll released over the weekend showed Sen. Barbara Boxer (D) leading Carly Fiorina (R), 50% to 42%. The same poll also found Jerry Brown (D) with an even bigger lead over Meg Whitman (R) in the state’s gubernatorial race, 52% to 39%.

* In Missouri’s U.S. Senate race, the latest Mason-Dixon poll shows Rep. Roy Blunt (R) leading Robin Carnahan (D) by a fairly comfortable margin, 49% to 40%.

* In Ohio’s gubernatorial race, a Dayton Daily News/Ohio Newspaper poll shows John Kasich (R) narrowly leading incumbent Gov. Ted Strickland (D), 49% to 47%.

* In Massachusetts’ gubernatorial race, a new Boston Globe poll shows incumbent Gov. Deval Patrick (D) with a narrow lead over Charles Baker (R), 42% to 39%. Independent Tim Cahill (I) is third in the poll with 8%.

* In Maryland’s gubernatorial race, Gov. Martin O’Malley (D) is starting to pull away in his rematch against former Gov. Bob Ehrlich (R). A Baltimore Sun poll shows the incumbent up, 52% to 38%, and the Washington Post shows O’Malley up by a similar margin, 54% to 40%.

* And in Minnesota’s gubernatorial race, a new Star Tribune poll shows former Sen. Mark Dayton (D) ahead of Tom Emmer (R), 41% to 34%. Independent Tom Horner is third with 13%.
