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.

* In a bit of a surprise, the latest Denver Post poll in Colorado shows Andrew Romanoff closing very strong in his Democratic primary against Sen. Michael Bennet, taking a narrow lead over the appointed incumbent, 48% to 45%. In the GOP Senate primary, Ken Buck leads Jane Norton in the poll by a wider margin, 50% to 41%.

* In Kentucky, a Bluegrass Poll conducted for the Louisville Courier-Journal shows Rand Paul (R) continuing to lead state Attorney General Jack Conway (D) in this year’s Senate race, 51% to 43%.

* Confirming several other recent surveys, the latest Florida Poll shows Gov. Charlie Crist (I) leading this year’s Senate race with 41% support. Marco Rubio (R) is second with 30%, followed by Rep. Kendrick Meek (D) with 12%.

* Speaking of Florida, Democratic Senate hopeful Jeff Greene fired Joe Trippi from his campaign team over the weekend. (Greene was also the subject of an extremely unflattering St. Petersburg Times profile, which ran yesterday.)

* As if Illinois’ Senate race isn’t quite odd enough, voters will apparently vote for a new senator and a temporary senator at the same time.

* In Minnesota, the latest poll from the Star Tribune shows former Sen. Mark Dayton leading the Democratic gubernatorial primary with 40%. Margaret Anderson Kelliher is second with 30%

* Interesting development in Texas: “More than a dozen prominent Dallas business and civic leaders, including several who supported Kay Bailey Hutchison in the Republican primary for governor, have signed a letter backing Democrat Bill White in his effort to unseat Republican Gov. Rick Perry in the Nov. 2 general election.”
