I think I said that. That's not the only thing it does. When it comes to Texas there's the idea that they might get a bigger share of the ad cash but this is in conflict with generally worse chances for the GOP candidates.
A better idea for a red state looking for ad cash would be to team up with one or more blue states of similar total size and move to an honest proportional EV system. The cash wouldn't be diluted as much either (at least initially).
By 'honest' I mean not the sorts of hijinks the GOP is trying out in VA (and elsewhere) where Obama would win the state vote and lose 2/3 of the electors. The problem there again is sooner or later some state get's kingmaker power by changing back to plurality = all evs.
Again, it's not about parties, it's about policies. The long-term average will always be for each major party to win about half the time because if they don't they'll change their policies until they do. The question is what policies they'll adopt in order to do it -- and if your vote doesn't count, whether you're Texas or New York, your voice isn't the ones they'll be listening to when deciding what policies to adopt. What good does it do a Texas social conservative to elect a GOP candidate like Mitt Romney?
I'm not sure what your point is. Where he differs from Obama, Romney's positions are nigh-universally closer to those of Texas social conservatives aren't they? What is the biggest issue for Texas social conservatives? Abortion? What office that a Texas social conservative votes for has more impact on the future of this issue than POTUS? Would Romney's Supreme Court nominees presumably be better or worse than Obama's from the POV of Texas social conservatives?
