However, Brown only holds the seat until 2012 and if the Dems put up a decent candidate we could be better off than Coakley being in there forever. If the economy is better, Obama could even have coat-tails again, helping get rid of what could very well be a 2 year Senator.
Yes, bad things could come of this, but the mid-term elections are still 9 months off and this was far more about Coakley actively trying to screw this up than any political realignment.
Here's what could happen as a result if good things come of it.
The Democrats no longer have a faux "Supermajority" to lean on, so they have to pass legislation normally.
Lieberman gets sidelined or even drummed out of the Democratic Party.
The Democrats will have to have some guts to get anything done, so they FINALLY dump Harry Reid from leadership.
In 2 years we get a much better MA Senator, one that is actually liberal!
