So wrong it's not even funny. The party has been broken for years. What you'll find is that Bush was the last straw in a very big haystack. Guess what happens when something completely breaks down? Those involved put the pieces back together and come out stronger than they were before. So, if anything, Bush's failed administration is the wake up call Republicans needed. Expect to see a strong candidate come out in 2016.
It all goes in cycles.
The Republicans will come back.
