'Chesapeake Primary' on Ice

Tuesday's primaries in Maryland, Virginia and DC, which drew high voter turnout despite a nasty ice storm in the afternoon and evening, gave boosts to John McCain and Barack Obama.

Also of interest were two Maryland congressional races where incumbents, one Democrat and one Republican, were turned out by challengers more liberal and conservative respectively. This appears to indicate the strong roles the base of each party play in determining candidates and party direction.
