Thursday’s campaign round-up

Today’s installment of campaign-related news items that won’t necessarily generate a post of their own, but may be of interest to political observers:

* Rick Perry, in an interview with the San Francisco Chronicle, said he was not intoxicated or on prescription medication during his strange speech in New Hampshire yesterday. He characterized his performance as “animated.”

* Herman Cain conceded that he “may have misspoke” when he said China is “trying to develop nuclear capability.” He told the Daily Caller, “What I meant was China does not have the size of the nuclear capability that we have.”

* Rick Santorum this week completed a rare feat: he’s now visited each of Iowa’s 99 counties. It doesn’t appear to be helping — the last Des Moines Register poll found the former senator running seventh with just 5% support.

* A new Franklin and Marshall College poll in Pennsylvania shows President Obama with double-digit leads over all of his Republican opponents, though the percentage of undecided voters remains very high.

* In North Carolina, the latest survey from Public Policy Polling shows Obama leading all of his GOP challengers except Romney, who leads the president by one point, 46% to 45%.

* In Maine, Sen. Olympia Snowe’s (R) shift to the right is helping win over Republican voters. The number of Maine Republicans who support the incumbent senator has jumped from 31% to 47%.

* In Texas’ U.S. Senate primary, featuring a crowded GOP field, Lt. Gov. David Dewhurst appears to have the early edge, leading former state solicitor general Ted Cruz by 12 points in a new statewide poll.

* And in the state of Washington, Darcy Burner, a netroots favorite, is launching her third congressional bid, running in a crowded primary to replace Rep. Jay Inslee (D), who is running for governor. In her first two congressional campaigns, Burner came up short against Rep. Dave Reichert (R).
