People are tired of Obama's failed policies. Since they cannot vote him out, they vote his party out.
The Repubs will need to fill the void. They need to have a real plan to make things different (hopefully better) or these gains will be short lived.
They should work right away to pass real tax reform, immigration reform and fix Obamacare. These are big items but they need to go big or go home.
Obama may veto everything but then the Dems become the part of "NO".
My fear is that the Repubs will end up squabbling among themselves and not get anything done.
It will be interesting...
