I'm fairly sure that the conservative base made up most of the people that were out there voting Republican. I believe that the news media played a large part in the size of the Democrats' win. The Democrats would have picked up seats in any event.
Regardless, this is still the same country it was on November 6. Remember that. There is no big change in the country, but in the composition of Congress.
It's the same country, but the rot at its core will accelerate with Dems in power.
