FUCK THE POLICE
911 EVERY DAY
If they win the WH they will hold the Senate. I see the Senate staying with the WH (or changing if a D is elected) as the people voting for President will be voting Party for the Senate as well. There will be more voters than we've had in any modern election, this will energize the populace as they are selecting two branches at once.
This election cycle will be for all the marbles, basically.
The 2016 election is going to be disadvantageous to the Republicans, because they're going to be defending the ultra-conservative 2010 slate of senators. This time they don't have the advantage of low voter turnout to boost them either.
