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.

* A coalition of unions have launched a new TV ad in Pennsylvania, taking on Arlen Specter for his opposition to EFCA.

* Republicans really seem to believe Senate Majority Leader Harry Reid is vulnerable in Nevada next year. They just can’t seem to find a credible opponent for him.

* In Florida, with Charlie Crist running for the Senate, the gubernatorial race will probably come down to state CFO Alex Sink (D) vs. state Attorney General Bill McCollum.

* Speaking of Florida, almost immediately after Crist announced, former House Speaker Marco Rubio launched an ad accusing the governor of being overly supportive of President Obama.

* John McCain is up for re-election next year, and while he’s likely to win another term, a new poll shows a plurality of Arizonans believe the senator is out of touch with his constituents.

* NRCC Chairman Pete Sessions’ (R-Texas) bizarre anti-Obama tantrum the other day is now the subject of a DNC fundraising effort.

* Utah Attorney General Mark Shurtleff accidentally announced that he’s challenging Sen. Bob Bennett in a Republican primary next year, indicating his plans in a Twitter message he intended to send to one person. Shurtleff tried to pull his announcement, but it was too late.
