I’m not sure of the best route, but I like the fact that there’s no “open” primary.
I’m worried about Dems going heavy for Mitty in open primary states, since they have no POTUS race (at least yet).
1)there is no way we can stop the Democrats from picking our candidate, so we must have a convention.
2)It will disenfranchise Independents
3)If Independents can vote for Republican, then Dems will just register as independents.
4)If we make Independents register as Republicans, they won't and the nomination goes to Romney
If Dims vote in the Republican primary, they should be prohibited from voting for a democrat in the general election that year. In other words, you should have to declare your party affiliation in the primary and that party will be the party you vote for in the general. Only the party regulars should be allowed to vote for their candidate.
