The problem with this 'centrist' position or to use your word, bipartisanship is that it speaks of compromise. That in and of itself would be considered good except we are at a place where 'compromise' now requires, in many cases, capitulation on core beliefs.
We no longer live in a society that has a common set of values. Take immigration for instance. Either you believe that the US is a sovereign nation with secure borders and the right to positively decide who comes in or you don't. Their is no middle ground in that belief. You just can't have 'half open' borders and still consider yourself a sovereign country. Being libertarian by nature I would like to see a world without borders but before we give up our absolute independence I want to be damn sure what world governance looks like... and I don't see power people turning loose of the reigns.. I only see power consolidation. So immigration is uncompromisable and we already had an amnesty with border security signed and broken back in 1986.... what was an amnesty for 3 million people turned into an illegal population of what 11 million?... 20 million?
Another subject is health care as a 'right'... either you believe that the US federal government has the right to charge you to be a natural born citizen or you don't... no middle ground issues their. So you see, until we actually all believe in the same set of values, ethics and standards, compromise is a very difficult thing to achieve without giving up on your fundamental beliefs of right and wrong and where government fits into your life.
