Evan Bayh's departure from the presidential race is not exactly the akin to the plates shifting under the San Andreas fault, but it could have some effect on the race for the 2008 Democratic presidential race.
The Washington Post's Chris Cillizza says the winners are:
Iowa Gov. Tom Vilsak - One less moderate midwestern governor
Iowa Gov. Tom Vilsak
llinois Sen. Barack Obama - Less competition for midwestern donors
Bayh himself - takes himself out of the race before it starts so as not to damage his Veep chancesNew York Sen. Hillary Clinton - she's positioned as a moderate and there's one less competitor now
Low-name-recognition candidates with strong resumes. If the resume didn't work for Bayh, it may not work for the others.
