The Republican party will not die any time soon, certainly not by the next election. There is no way that will happen and that's all there is to it. In 2008, people liked Obama more than they like Democrats as a whole. Even more than that, they were tired of Bush. Even so, Obama I think only won like 53 % of the popular vote. Just give him time to foul up something and the Repubs will jump at the chance.
