McCain might have even won without the financial crisis. On the day that it started he was leading in all the national polls.
Just like Mitt Romney!
I believe that Hillary would be the Nominee, not Obama.
Obama was the nominee before the financial crisis so no, she wouldn't have been.
I think its fair to say that McCain would have done the same as Romney if there was no crash. Heck, we didn't know how bad the crash was until everyone was fired or couldn't get a job that spring/summer. Unemployment was 6.8 on Election Day and at 8 by the time Obama took office...and by the end of that summer it got to 10. McCain would have probably lost Montana, Missouri and Georgia if we knew the gravity of what was happening then.
