It's pretty sad to think that democrats may take over. I myself am not republican but rather a libertarian. I hope in the next few years more parties will rise which voice our peoples' opinions accurately. Its scary to think that one party might eventually rule the USA, they would have too much power and power is not necessarily a good thing. I foresee a civil war coming.
I find it laughable how quickly Americans just to armed conflict being a result of their politics... No you won't have a civil war, other groups will come in and fill the gaps. Either the Republicans will change out of necessity or new parties will come. Ultimately if one party adapts and the other refuses to, then the one that refuses to should die out, just as with evolution.
The best solution would be to introduce a proportional representation system. Then new parties can come and go, split or form with much more freedom and still get a share of the vote.
