brinkmanship

why do democrats keep a bipartisan approach when the republicans are recalcitrant and uncooperative, is unseating Obama more important than bringing default to US credibility.? Bachman and company insist that paying only the debt interest is acceptable and slash social programs in the next session. It is the most stupid position that any politician worth his/her salt can bring up, don't they know this is the same schema that wrought the sub prime rate debacle, or fascism and racism the main staple of the conservatives?
