Tonight's Primary Election Results

UPDATE: 8:39 pm PDT
There are four races that I'm watching:

Kentucky GOP Senate - Rand Paul wins big.  The candidate backed by Sarah Palin and James Dobson beats the candidate backed by Dick Cheney and Mitch McConnell.  Conservatives over GOP elites.  Unless Paul blows up along the way he should win in November.
UPDATE - This headline says it all:

'I HAVE A MESSAGE FROM THE TEA PARTY: WE HAVE COME TO TAKE OUR GOVERNMENT BACK'...

Arkansas DEM Senate - 59% in and Lincoln now trailing 43%-43%,  50% needed to avoid a runoff.

Pennsylvania DEM Senate - Race has been called for Joe Sestak.  Arlen goes from Specter to Spectator.  Sestak will face conservative Pat Toomey in November.  From The Fix:

If Specter loses, the day he lost it was the day he switched and said "my change in party will enable me to be reelected."

Pennsylvania House District 12 Special - It's as good as over.  Mark Critz will win and PA-12 will stay in the Dem column. The big turnout for the Dem Senate race undoubtedly hurt Burns, but he also underperformed in a lot of key parts of the district.  The heavy Dem voter registration advantage in this district paid off.
