Sooner or later the harsh realities have to be faced. Why not face it now? Obama thinks Republicans will be blamed. Maybe....maybe not. Obama is in the White House and his party controls the Senate. Why not fight the good fight right now. Go over the cliff and do not raise the debt ceiling. Force the country to come to grips with the debt situation while it is still possible to do something about it.
By coming to a fictitious agreement that may seem politically advantageous in the short run, such an agreement gives up on the country. Letting the national debt spiral out of the control, which is the Obama plan, destroys the American economy and potentially it's political fabric. Why not tackle the issue now while Republicans control the House and can block any further madness by the Obama Administration. The future isn't very bright either way, but there is no hope for the future if Republicans cave in here.
The time is now.
