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.

* In California, the latest survey from Public Policy Polling shows Sen. Barbara Boxer (D) building on her earlier lead, and now has a nine-point advantage over fired HP CEO Carly Fiorina (R), 49% to 40%.

* On a related note, PPP also found that state Attorney General Jerry Brown (D) leads former eBay CEO Meg Whitman (R) in California’s gubernatorial race, but the leading is shrinking. Brown is now up by six, 46% to 40%.

* In New York, a new Quinnipiac poll shows state Attorney General Andrew Cuomo (D) continuing to enjoy huge leads in his gubernatorial race, leading former Rep. Rick Lazio (R) by 30 points, 56% to 26%,

* Oklahoma will have its first woman governor next year, after yesterday’s gubernatorial primaries. Rep. Mary Fallin, as expected, won the Republican nomination, and in a bit of a surprise, Lt. Gov. Jari Askins edged state Attorney General Drew Edmondson for the Democratic nod.

* As of this morning, former Rep. Rob Simmons’ (R) on-again/off-again Senate campaign in Connecticut is back on again.

* If you’re inclined to believe Rasmussen, Illinois state Treasurer Alexi Giannoulias (D) has a narrow lead over Rep. Mark Kirk (R) in this year’s Senate race, 43% to 41%.

* In an interesting Democratic primary in Tennessee, Rep. Steve Cohen (D), a white lawmaker running for re-election in a majority-African-American district, now enjoys support from the Congressional Black Caucus for the first time.

* It almost certainly won’t amount to much, but Rep. Mike Castle (R), the leading candidate in Delaware’s U.S. Senate race, is facing a primary challenge from Christine O’Donnell. Yesterday, O’Donnell picked up support from the Tea Party Express, which has previously helped right-wing candidates in GOP primaries in Nevada, Kentucky, and Utah.
