WEDNESDAY’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.

* While the right is targeting House Democrats who supported cap-and-trade legislation in June, four independent groups — the League of Conservation Voters, the Sierra Club, MoveOn and Americans United for Change — are targeting five House Republicans for opposing the same bill.

* Speaking of ads, the DNC is launching a new radio ad campaign, applauding 13 House Dems for supporting the stimulus package and S-CHIP.

* Last week, New York Gov. David Paterson (D) seemed to suggest that racial bias in the media has played in a role in the criticism of administration. Yesterday, he walked it back.

* Virginia gubernatorial hopeful Creigh Deeds (D) is launching a new radio ad, intended to bolster Deeds’ support among African-American voters. The minute-long spot, called “Fired Up,” features President Obama’s praise for the state senator.

* In California, two new polls show San Francisco Mayor Gavin Newsom trailing state Attorney General Jerry Brown in the Democratic gubernatorial primary by wide margins. Of particular interest were results showing Newsom trailing Brown in San Francisco, which should be the mayor’s strongest area.

* And in Connecticut, Joe Lieberman responded to the possibility that actor Alec Baldwin might run against him in 2012. Lieberman taunted Baldwin on CNN, saying, “Make my day.” In a statement, the actor said he has no plans to run for office, but added, “Part of me would hate to see Lieberman go…. There are so few moderate Republicans left in the Senate today.”
