I guess it depends on how broad your spectrum is.  The individuals may indeed be competent and qualified people - but only the most hyper partisans in the crowd would suggest that those selected are a diverse group spanning the spectrum.  All but perhaps 2 scream social advocate for causes embraced by the left.

This whole independent senator bit is nothing more than attempt to placate the more gullible.  People drawn to serve in institutions like the House and Senate are political people with established partisanship.  To suggest that they will check their beliefs and partisanship at the door is absurd to say the least.
