Let me revise my earlier statement. I might actually vote the democratic ticket if the house and senate are still both republican majority. I'm no fan of the current democratic party, don't get me wrong, but bad things happen when the same party controls both the legislative and executive branch.
My perfect government would be one where either the president is a democrat and congress is republican or where the president is republican and congress is democrat.
Why?
Simple. New laws are less likely to be passed, more things will probably die in committee or get a veto (pocket or otherwise). I'm pretty sure there are some things that can make life better, but more laws ain't the answer, so let's have some checks and balances so that government can be a little less 'productive'.
