Just from the Ds' POV, Pelosi, Reid, BHO, and HRC have been horrible leaders. The Ds lost control of the House, lost control of the Senate, lost the WH, lost a chance to flip the USSC Lib/prog, face the likelihood the USSC's weather vane could be replaced with a solid Constitutionalist, and could see a 4-1-4 or 5-4 Constitutionalist court go 5-1-3 or 6-3 Constitutionalist.
Just from a D POV, Pelosi has been a failure for some 7 years. MM has swum so far up the proverbial Egyptian River he's seeing Ramses II face to face at Abu Simbel.
