An election never decides what's right, only what the majority population WANTS. Had the GOP lost the House, then you'd have a point here. Also, given the popular vote count, your 'adult' point is silly.
Still, I say rubber stamp all that the Dems want. YOu wanna see firsthand what the result will be? Be my guest. Just be sure to look in the mirror when bad things happen. If you're willing to be accountable, I'd tell the GOP to push it all through. Of course, NO Dem would be willing to do that. Without SOMEONE else to blame, Dems will never be bold or implement what they say they want.
