The TPM Electoral Scoreboard right now shows Obama 251, Romney 206. Keep in mind, the map is based on the latest polling in PollTracker, so the numbers are always changing. It’s a snapshot.

Toss up is defined as a margin of 2 points or less separating the candidates in the PollTracker average of polls for that state. Take a look.
