McCain is campaigning in states that he is likely to lose in the double digits. Why? Do secret internal Republican polls tell another story? Unlikely. John McCain is almost pathologically obsessed with Teddy Roosevelt, and romanticizes the idea of the rough and tumble pol who bends others to his will. This is something that doesn't exist, if ever. In reality things operate more like LBJ in the senate, with careful cajoling and bargaining.
But McCain thinks that he has so much force of will, so much fortitude, that he can bend events with his mind. That's why he did the whole campaign "suspension" trick, and that's why he's campaigning in states he will lose.
