These committee chairmen are all creatures of the Great Society and what was called the New Left of the 1960s and 1970s. They have spent their lives in government and know almost nothing about the private sector or how to grow an economy. They view the Reagan era as an historical aberration, and they have stayed in Washington for decades precisely in wait of this moment to realize 40-years of pent-up policy ambition. They believe this is their 1965, or 1933.

While Mr. Obama campaigned as a young postpartisan Democrat who wanted a new era of comity in Washington, his victory has instead empowered these ancient left-wing warriors. These are the men who have run Washington this past year, and they are Mr. Obama’s de facto cabinet…

It is the combination of all of these and other policies that has ignited the political revolt we are now seeing in Massachusetts, and first saw last November in Virginia and New Jersey. Had Democrats modified their agenda to nurture a fragile economy and financial system, they could now claim their policies worked and build on them later.

Instead, their frenetic agenda has frightened voters and businesses about the vast expansion of government power and enormous tax increases to come.
