This source contradicts your assertion. It says both Obama & McCain persuaded their fellow senators to vote for the bailout. Why did McCain have to suspend his campaign and Obama managed without having to do that?
McCain's support was critical..or else Graham and Paulson wouldn't have asked him to come back.
That "or else" doesn't follow at all. You just admitted McCain, as the presidential candidate, is the most important man for the party, so it seems likely that Graham & Paulson asked him to come back to make him
seem critical to the electorate - a political ploy.
He did get Repub support for the bill..Pelosi wouldn't have brought it to the floor without Repub support and he got enough Repubs to come across the aisle.
How do you know that it was he who got Republican support for the bill and not Bush, Paulson, Graham, Kyl or McConnell?
From your source above:
In Missouri, before flying to Washington to vote, McCain said, "If we fail to act, the gears of our economy will grind to a halt."
Why was he in Missouri just before the vote? Was he....
campaigning?
