The polarization The (Washington) Post editorial board decries is a reaction to the radical agenda Obama is pursuing in our nation’s capital. Obama has eschewed the bipartisanship pursued by his predecessors, President Bush (No Child Left Behind) and President Clinton (NAFTA, welfare reform), in their first years in office. Instead, he has pursued a maximalist liberal agenda and refused any real compromise. When you pass a radical overhaul of health care along strict party lines, using clever parliamentary tactics to avoid compromise with the other party, it’s going to have a ripple effect across the electorate. link
The Washington Post is not known for its conservative leanings.
