All over in the US
Colin Powell has endorsed Barack Obama, and even before that happened Obama has a commanding lead not just nationally, but in the state polls.
There were 18 states in 2004 that had a margin of victory of less than 10%. Every single marginal state, except Arkansas, has Obama in the lead in state polls.
Obama needs 269 electoral votes to win. At present he has 286 locked in and 364 likely. It would need something massive to happen to stop him.
