Is the presidential election over?

The Obama campaign is working hard at winning Virginia, North Carolina and Florida. The first two are Republican strongholds which have not gone to the Democratic presidential candidate since 1964 (LBJ landslide). Bush won Florida twice. If Obama wins two out of those three, I don’t see how McCain can win the White House, unless he snags Wisconsin and Pennsylvania while holding onto Missouri. The McCain camp already conceded Michigan and is far behind in Minnesota, a Democratic stronghold where it thought it could compete.
