You still think something can happen at the convention? Here... The important part of this is: 1. 80% of delegates come from Primary states, 2. more than 80% of those delegates will be
pledged, 3. those states are almost all winner-take-all, 4. McCain gets to research and approve (choose basically) all those delegates, 5. Ron Paul only got 5% average in all those primaries, and did not win any of them outright.
The most important part is: 86%-95% of the voters and delegates
voted for a pro-war, non-Paul candidate. Even if we won half of Romney's people and half of Huckabee's people (extremely, ridiculously, stupidly unlikely) we would still only have like 30% of the delegates. And 80% of Republicans pro-war (thus very anti-Paul), so they would never vote for Ron Paul--even if McCain died, and Romney and Huckabee--it doesn't matter--they would choose many other people before they would ever choose Ron Paul.
