Maybe I'm just naïve, but I am surprised by this response as well, and would be surprised if the election didn't happen.
Honestly, it just feels like status quo for the parties. With 3 branches of government and a 2 party system, one party usually has 2 of 3 branches. I think it's dangerous for 1 party to have all 3. I just feel like every election cycle it's the end of the world for one of the parties. In fact, I think only Regan and Bush Sr didn't have the party support in congress for part or all of their terms.
