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.

* Texas Gov. Rick Perry easily won his Republican gubernatorial primary yesterday, defeating Sen. Kay Bailey Hutchison by more than 20 points. Hutchison conceded last night, and there will be no runoff.

* On a related note, Texas Democrats nominated former Houston Mayor Bill White as their gubernatorial nominee. Despite the state’s obvious political leanings, the Democratic Governors Association released a memo yesterday entitled, “Why Democrats can win Texas.” It touted White as an “outsider who can bring people together” while portraying Perry in the Republican primary as having “sprinted to the far right.”

* As for Kay Bailey Hutchison, she announced her plans months ago to step down from the Senate, whether her gubernatorial campaign was successful or not. While Republicans in D.C. hope to convince her to change her mind, if Hutchison keeps her promise, Perry will appoint a temporary senator to serve until November.

* Billionaire media mogul Mort Zuckerman announced yesterday that he will not run for the Senate in New York this year, despite Republican overtures. The announcement came just a few hours after a statewide poll showing Zuckerman trailing Sen. Kirsten Gillibrand (D) by 33 points.

* Businessman Jon Ashjian today filed to run for the Senate in Nevada on the Tea Party ballot line, all but assuring a three-way contest in Senate Majority Leader Harry Reid’s re-election bid.

* In Pennsylvania, a Quinnipiac poll shows state Attorney General Tom Corbett as the leading Republican gubernatorial candidate. There are several candidates in the Democratic field, but the poll shows no clear favorite.

* The AFL-CIO is working on creating a “firewall” strategy that the union hopes will help prevent a Republican takeover of Congress.

* In Georgia, former Gov. Roy Barnes (D) is running to get his old job back, and the latest survey from Public Policy Polling shows him with narrow leads over the GOP field.

* Former Rep. Joe Schwarz (R.), defeated in a GOP primary a few years ago for not being right-wing enough, is launching a gubernatorial campaign in Michigan this year.
