The Iowa caucuses are tonight! Coverage starts at 7 pm EST on CSPAN. Never have I been more sorry I didn't focus my job search on the Des Moines area.
Some stuff to get you in the mood:
A really excellent article by Andrew Sullivan about Why Obama Matters.
A David Brooks column about why Romney's old-school Reagan Republicanism could make him unelectable in the fall (NY Times free registration required)
In case you haven't seen it, Mike Gravel has given us the single greatest political ad ever made.
