[Mr. Morden]

MO-PRES 2008, almost.

Not just the GE, but the Democratic primary as well:

In general, I'd think that Democratic primaries would be especially prone to this kind of behavior, since the population of voters is even more concentrated in urban areas in Democratic primaries than it is in a general election.
