Since you posted that, things have changed. Obama now needs to win 27 of the 125 toss-up votes, while Romney needs 100. Wisconsin moved into the toss-up category. I also note that there are 82 electoral college votes in states that lean Obama, while there are only 39 in states that lean Romney, and 36 of those latter (Indiana, South Carolina and Georgia) seem pretty safe GOP havens to me. Of course, some of the "lean Obama" states seem secure for the Democrats: NJ, Michigan and Oregon are unlikely to turn red.
Huffpo also has an electoral map, and in their projection Obama has 284 electoral votes to Romney's 170.
The main differences are that RCP has Iowa and NH as toss-ups while Huffpo has them as strong Obama, and Huffpo puts VA and OH in the leans Obama category while they are toss-ups according to RCP.
