Thanks for sharing that with us. It's a pretty good perspective on things...but it ignores one major point: the tendency or inclination by the out-of-power party lately to obstruct rather than govern. While obstructing may gain 'points' with its core constituency, it abrogates its responsibility to govern. Congress is not participating in governing.
As low as the president's approval ratings may be, Congress -- especially the Senate -- can hardly brag about its standings...they're way lower.
I maintain that the country is not divided and dysfunctional -- it is the gerrymandered/my-district-is-safe crowd who are pawns to the special interests. Special interests include a whole raft of folks, from pharma to health insurance to defense contractors to Wall Street to realtors and countless others.
Who is representing those of us who voted them into office?
