WEDNESDAY’S CAMPAIGN ROUND-UP…. Today’s installment of campaign-related news items that wouldn’t necessarily generate a post of their own, but may be of interest to political observers:

* In one of the nation’s largest recall campaigns ever for a local election, Miami’s Republican mayor, Carlos Alvarez, was easily thrown out of office yesterday.

* Speaking of South Florida, scandal-plagued Rep. David Rivera (R) is facing so many scandals, Republicans in Washington and Miami are already drawing up lists of potential primary challengers. Rivera was elected last year despite ongoing ethics allegations, and is now the target of an expanding criminal investigation.

* In Nevada, Lt. Gov. Brian Krolicki (R) had considered running for the Senate, but instead yesterday threw his support to Rep. Dean Heller (R), who launched his own Senate campaign this week. Krolicki will instead probably run for Heller’s U.S. House seat.

* As Ohio sours on its new Republican leadership, Sen. Sherrod Brown (D) appears to have benefited. A new survey from Public Policy Polling shows the incumbent senator now leading prospective GOP challengers by margins ranging from 15 to 19 points.

* Last year, Rep. Betty Sutton (D) beat Tom Ganley (R) in Ohio’s 13th district, and it’s unlikely we’ll see a rematch next year — Ganley was indicted this week on three felony charges of gross sexual imposition and single counts of kidnapping, abduction, solicitation, and menacing by stalking. Ganley was a top Republican recruit in 2010.

* In Connecticut, Rep. Chris Murphy’s (D) Senate campaign got a boost yesterday when the entire Connecticut House delegation threw their support to him. Murphy is facing former secretary of state Susan Bysiewicz in a Democratic primary.

* Tea Party activist Laureen Cummings launched a Senate campaign yesterday in Pennsylvania, and hopes to take on Sen. Bob Casey (D) in 2012. Though the GOP field is expected to grow, so far, it’s limited to Cummings and former Rick Santorum aide Marc Scaringi.

* And in Wisconsin, thanks to a backlash against Gov. Scott Walker (R), the enthusiasm gap that Republicans enjoyed appears to have vanished.
