FRIDAY’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 Nevada’s closely-watched Senate race, a new Mason-Dixon poll shows Senate Majority Leader Harry Reid (D) leading Sharron Angle (R) by just two points, 46% to 44%.

* In Florida, disgraced former health care executive Rick Scott’s (R) scandalous past seems to be catching up with him. As more revelations come to light, his once-strong standing in the Republican gubernatorial primary is falling apart, and a new Mason-Dixon poll shows him trailing state A.G. Bill McCollum, 34% to 30%. As the two GOP gubernatorial candidates continue to slam each other, state CFO Alex Sink (D) now leads both Republicans in hypothetical match-ups.

* In a display of post-primary unity in Colorado, former state House Speaker Andrew Romanoff joined Sen. Michael Bennet for a rally yesterday, endorsing his Democratic rival and urging his supporters to focus on helping elect Bennet in November.

* On a related note, Rasmussen, unlike other recent independent polls, shows GOP oddball Ken Buck leading Bennet, 46% to 41%.

* The gloves are coming off in Louisiana, where Rep. Charlie Melancon’s (D) new ad goes after Sen. David Vitter (R) for hiring prostitutes, having a weak legislative record, and for hiring an abusive criminal to oversee women’s issues.

* While most polls in California show Sen. Barbara Boxer (D) leading in her re-election bid, SurveyUSA shows failed former HP CEO Carly Fiorina out in front, 47% to 42%.

* Speaking of California, SurveyUSA also shows former eBay CEO Meg Whitman (R) with a narrow lead over state A.G. Jerry Brown (D), 44% to 43%.

* And in case there were any doubts, Sen. Dick Lugar (R) will seek re-election in 2012.
