> I doubt that granting Congress more power will inspire them to be less political,

I'm not sure I can wrap my head around the expectation that a political institution should be 'less political' -- can you explain what you are getting at here?

> more governed by facts.

Fact substantiate 'is', but politics is about 'ought', and particularly, reconciling the contradictory 'ought's that prevail in varying quarters of society. Expecting politics to be 'governed by facts' requires taking a single set of values and interests for granted, which effectively means codifying one faction's ambitions into law at the expense of everyone else.
