When a President starts coming up with illegal agendas like amnesty by memo and obstructing his opponents by using the IRS (somethinng Richard Nixon was nearly impeached for), destructive programs like Obamacare, and weird wishful thinking like backing the Muslim Brotherhood in middle Eastern countries, it's up to the other branches of govt to stop him. The people who wrote the Constitution called it "checks and balances".
Once the American people got enough of Democrat lawlessness and contempt for the Constitution, and started handing majorities to the Republicans instead, the Republicans started to do exactly what the Founding Fathers intended: Block Obama's destructive and un-American agenda. Now, with majorities in both the House and the Senate, they will be able to do that job more completely, as intended by the Constitution. They will be able to save the country from the Democrats' crazier programs, as they have been doing to some extent already.
A "do nothing" Congress is bettter than a Congress that exposes the country to the depredations of a lawbreaking, ideologically insane President.
And now that Republicans have majorities in both houses, they will be able to discard the "do-nothing" policies of Harry Reid, who stonewalled and bottled up hundreds of bills successfully passed by the House.
The only "do-nothing" part of government for the next two years, will be that lawless President, who can be expected to veto every bill passed by the Congress (as the Ameican people voted for on Nov. 4) that sets the country back on the right track, and away from what Obama intended.
Only a COMPLETELY lawless President will be able to evade the checks and balances built into the U.S. Constitution, by deliberately violating that document's laws.
And he won't be able to evade them for long.
