Then...
Absolutely nothing for six weeks until Pennsylvania on April 22. Shit. Atrios and Booman may actually have a say this primary. How scary is that? And those 188 delegates will loom large. In fact, this is the only contest of significance (not including Guam) for an entire two months. It'll be huge.
I was discussing this with a friend last night. While we've been assuming that our little primary votes won't be especially important, due to the calendar if it actually does drag on that long the national campaigns will essentially pack up and move to PA for a month or so.
That'll be really weird.
