Ron Paul's delegates have been kind of aced out at the Republican convention. You can get the story at Democracy Now. For Romney the best political strategy is to enrage any faction within the party that doesn't tow the line 100%. I think a lot of Ron Paul supporters that would have considered voting for Romney as the lesser of two evils now will not consider that.
It's pretty frustrating I imagine. People often ask Ron Paul why he doesn't just run as a liberterian. He disagrees so much with the Republican platform. His answer is that he just knows it's fruitless. The system is rigged to prevent any third party success. He doesn't want to spend all his time trying to figure out ballot access and red tape. He wants to spread his message. To do that successfully he has no choice but to work within one of the two parties.
So Paul did that. The rules are rigged against him, but he used those same rules to get lots of delegates out of Maine and get himself a voice at the convention even though he did not win the popular vote in Maine. But that doesn't matter. Now the RNC has just changed the rules when it turns out they are used against Romney. They just told Maine's delegates they can't be seated.
It's a tough situation for Romney. He'd like to think everyone within the party is happy with his nomination. That would be ideal. But that's not reality. Politically is it wise to just rig the rules to silence dissenting voices so you can have the illusion of unity? Why not instead allow people to express disagreement, but then reach out to them and say that yes, you know you have disagreements, but you still want their vote and you can still agree that Obama is more harmful? We all know what Paul thinks of Romney. We all know that his supporters have problems with Romney. Preventing his delegates from having involvement isn't going to change that.
I think it is the kind of thing that will help some of the Paulites recognize that the Republican party has real contempt for democracy and will certainly subvert it if necessary. This is something Democrats have known for a long time. Consider the events surrounding Mike Connell and the 2004 election. The party elites and big money behind them are going to try and win by any means necessary.
