Nothing. Look at this thread; People don't care about politics. They care about elections. They're already talking about whom is going to beat whom in 20 months. And after that, all they'll talk about is OMG 2016 HILARY VS CHRISTIE or whoever ends up running.
No one gives a damn about the issues.
This isn't fair. Elections and the prospect of elections are what get issues taken care of. I'd like immigration reform to get passed. But immigration reform passing depends on Republicans deciding that it's in their political self-interest to support immigration reform. The situations faced by Republicans in future primary and general elections are very nearly determinative of immigration policy before 2015.
One can also look at Congress or the Supreme Court right now and reasonably conclude that by far the most important thing for Democrats, if they want to achieve particular policy goals, is to win more elections. Many Republicans appear to be totally incapable of compromising in a mutually satisfactory way, and there's nothing to do but vote them out. It's just not unreasonable to think that the most important thing to do, for the purpose of securing the country's welfare into the future, is to break the Republican party.
