Well it was expected they would take the House. The important thing is that their majority stays low and that the Repubs keep the Senate.
Many of the Democrats who won tonight campaigned as conservatives, and perhaps for a good number of them, that will be true and they will not walk in lock-step with Pelosi and the BendOver.org'ers. They may not get positions of power right away, but if they are conservative or moderately so, they can erode the leftist socialism pervasive in the Dem party today.
Second, impeaching Bush is not a high priority for many Americans, and it's not what they want. Dems who try it will find out what the Republicans learned in 1998 from the failed attempt at impeaching Clinton.
Also, in relation to the above, politics as we all know is a give and take proposition. If the Dems go whole-hog on impeaching Bush or rasing taxes or not funding troops (which by and large the vast majority in this country do not want to see regardless of their feelings on Iraq), the Republicans can fight back by not voting for legislation with earmarks favoring the Democrat districts of the various Dem Committee members.
The alleged Dem control of the House is not veto-proof. Bush can torpedo any Dem legislation he feels will harm the economy and veto any attempt to de-fund the troops. The Dems will not be able to override. Bush can then use the "look who wants us to lose the GWOT" and "look who's shutting down the government" similar to the tactic Clinton used.
Finally the Democrats will have to show something for this in two years, something favorable to a large majority of Americans or they will be out.
This is not the end for us but the start of a way to reform the Republican party and shake the RINO's out of the complacency they've had. But I admit it came at the price of losing a few good conservative politicians.
Finally a message to Nancy Pelosi, enjoy your victory but remember these words from 'Patton':
For over a thousand years, Roman conquerors returning from the wars enjoyed the honor of a triumph - a tumultuous parade. In the procession came trumpeters and musicians and strange animals from the conquered territories, together with carts laden with treasure and captured armaments. The conqueror rode in a triumphal chariot, the dazed prisoners walking in chains before him. Sometimes his children, robed in white, stood with him in the chariot, or rode the trace horses. A slave stood behind the conqueror, holding a golden crown, and whispering in his ear a warning: that all glory is fleeting.
