TUESDAY’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.

* At the urging of Fox News’ Glenn Beck, Conservative Party congressional candidate Doug Hoffman “un-conceded” the race in New York’s 23rd. Two weeks ago, Hoffman apparently lost the race, but some spreadsheet errors have since narrowed the margin of his defeat.

* For what it’s worth, it still seems exceedingly unlikely that Hoffman will overcome the vote deficit.

* In Iowa, a new Des Moines Register poll offers awful news for Gov. Chet Culver (D), who’s seeking re-election next year. The incumbent’s approval rating is down to 40%, and in a hypothetical match-up against former Gov. Terry Branstad (R), Culver now trails by 24 points, 57% to 33%.

* Speaking of Iowa, the same poll shows Sen. Charles Grassley (R-Iowa) with a big lead over Democrat Roxanne Conlin, 57% to 30%. Conlin last sought statewide office 27 years ago, and many Iowans don’t remember her — Conlin’s name I.D. is only 62%. Grassley, however, did not win over voters during his antics during the health care debate, and only 39% of Iowans approve of his handling of the issue.

* In Kansas, there’s a heated gubernatorial Senate primary between two Republican members of the U.S. House, Jerry Moran and Todd Tiahrt. At this point, Moran appears to be pulling away.

* Alexi Giannoulias’ (D) Senate campaign in Illinois continues to pick up steam, earning a big endorsement yesterday from Rep. Jan Schakowsky (D-Ill.).

* If former Sen. Norm Coleman (R) runs for governor next year, a new Rasmussen poll shows he’ll be the frontrunner for the GOP nomination. It would be Coleman’s second run for the job — he lost to Jesse Ventura in 1998.
