Assuming Obama wins what are considered "solid blue" states right now, he will have a solid 238 delegates. Those states are:
Here are some possible options:
[PA 21 or OH 20 + VA 13= 33/34]
[PA 21 or OH 20 + CO 9 + NV 5 or NM 5= 35]
[NV 5 + CO 9 + NM 5 + VA 13 = 32]
(Note: This doesn't even include Florida, North Carolina, Missouri or Indiana!)
The point is twofold. Obama can actually win without Florida, Ohio or Pennsylvania. If he takes any one of those, its virtually impossible for him to lose.
But only if you VOTE.
