That's a pretty idealized view: The vast majority of voters just want competent governance, with guard rails to make sure the governors don't go too far, because they (the voters) have lives to live and other things on their minds.
As to persuading voters, we should remember the joke about Islamist parties' agitation for "democracy": One man, one vote — once.
If we wanted “competent governance” we would just have China or Singapore run our country.
But yeah, "opinions are greater than facts" is technically a very democratic way to do things.
Would you rather the "holistic healer" who says only drinking green juice for a week to "detox" your kidneys make laws? Or the person who actually went to med school for 12 years.
Let's just replace the government with a Magic 8 Ball.
Now imagine what unelected government officials who play the revolving doors game with the industry they're supposed to regulate can do.
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.
I doubt that granting Congress more power will inspire them to be less political, more responsible, and more governed by facts. Particularly when the party that made this decision has veered completely in the opposite direction.
If anything, it will be used to prioritize "faith" over fact, like what we've seen in Oklahoma and Mississippi.
