Useful, interesting stats about elections.

No, I'm not going to give you a bunch of charts or numbers.  I'm merely pointing to two sources of national election information and registered voter demographics -- stuff you bookmark under a political folder for future reference.

• Annual elections -- The Office of the Clerk of the House of Representatives has tracked each election since 1920.  It includes a vote breakdown by state.
• Voter registration demographics -- The US Census Bureau tracks the demographics of people who register to vote, and whether they reported back that they voted.

Useful stuff, if you're into politics.
