It's called seeing the writing on the walls.
Geez, it seems the Dems see the tidal wave clearer than the establishment GOP.
We're pissed. Americans, even though they likely don't know the term "Keynesian" economics, understand inherently that you can't spend your way out of debt. I mean, you can't do that in your personal life, so how in the world could a government do it? Both Democrats and Republicans are using this approach, and people are sick of it.
Thus, the momentum of the non-establishment movement of fiscal conservatism, tighter immigration standards, and traditional American values.
I love that both sides are scared out of their minds. Even if the Republicans take over both houses, they aren't safe either. Voters are kicking ass and taking names.
