A surprisingly big day of news today...
AR-Sen: LG Mark Darr (R), whose name had been connected with possible runs for Governor and Senate, as well as a potential AR-3 bid had Womack left the seat, is surprisingly looking more like a Senate than a Gubernatorial candidate. So far we just have rumblings from sources, but Darr doesn't deny them - so it looks like he's in. Darr is a decent candidate but does not have a very high profile, so I'd guess the odds are around 50-50 that another Republican enters the primary field.
MA-Sen: Count another name cleared from the D field in favor of Markey. Rabbi Jonah Pesner, who had explored a Senate bid, is not running.
SC-1: Looks like there will be a Colbert for Congress after all. Elizabeth Colbert-Busch, Stephen Colbert's sister, is running as a Democrat. Despite her famous last name, she is not expected to be a factor in the heavily Republican seat. She may not even win the primary here, as businessman Martin Skelly is also in on the D side, and has loaned himself $250K.
GA-12: Some group I've never heard of is "attacking" John Barrow for being pro-gun in a rural, pro-gun district.
MA-Gov: In the second LG-related surprise of the day, LG Tim Murray (D) will not run. Murray was initially seen as Patrick's heir apparent due to his strong base in Central Mass and his position as LG. But Murray's life in the political fast lane came to a crashing halt after he crashed his car under suspiscious circumstances in November 2011 and became extremely evasive surrounding the crash. Later allegations of a close relationship with an overpaid housing official in Chelsea have damaged his credibility further. At this point, it's very unlikely he would have won a general (or even a seriously contested primary) so this is best seen as bowing to the inevitable.
TX-Gov: San Antonio mayor Julian Castro, Democrats' strongest potential candidate, won't run. Castro, like any TX Democrat, would need a perfect storm to win this race so it's not too surprising he would opt out.
NY-SD-46: After counting less than 100 additional ballots, Cecilia Tkaczyk (D-Duanesburg) has reversed George Amedore (R-Rotterdam)'s lead in this race, claiming a 19-vote victory. This outcome means... well, very little, because 6 Democrats have formed a coalition with Republicans. What this mostly means is that the leader of 5 of those six, Jeff Klein (ID-Morris Park, Bronx), gets more influence, since his votes are necessary to preserve the majority. New York is about to experience a radically different form of government... instead of three men in a room, it will be (gasp) four men in a room!
VA-LD-74: State Rep. Joe Morrisey (D-Richmond) brandished an AK-47 on the house floor. Legislators are allowed to bring guns into the capitol.
WATN: Former New Orleans mayor Ray Nagin (D) has been indicted on bribery charges.
