Was the Democrats losing the House a savvy political move?

For the Democrats to let go of the House was it more a savvy political move? When you think about it, if going forward Obama’s change is stagnant or stalled still the Democrats can point their fingers and say it was the House that stalled things. As it was the Democrats owned everything so any failure to get stuff done could not be placed on anyone’s head but their own. With them losing the House don’t that now give the Democrats a convenient scapegoat to take the heat when policies and programs fail?
