Jay Cost, who writes analysis for RealClearPolitics, has a nice piece looking at why gridlock continues in Washington, particularly with respect to the so-called "fiscal cliff." His conclusion, it will continue.
My conclusion: the American people want more government than they are willing to pay for. They want somebody else to pay for their government services. Naturally, "somebody else" doesn't want to pay up either. See this Washington Times article for more.
