I'll have more on the whole DeLay thing later (on a personal note, he picked a really crappy day from my perspective to suddenly resign), but for now, here are two links to give you some reading material in the meantime:

Matt looks at how things may shake out in the coming months.

Vince has an old-school mega-blog-roundup of just about everyone's reactions and thoughts. You want to be busy reading for awhile, start there.

More later from me, I promise.
