I hope that if term limits ever become a thing, it would only take a few elections of well informed voters to start making the change.
I think that congress is supposed to be a fluid body of people that are supposed to represent the population, and change as the population's interests change.
What we have now is career politicians making it to congress, and then milking it with all the donations, re election groups and lobby groups funneling them money making it very hard to actually enact any real change.
Even if one or two people make it to congress that are young and full of ideas/change they cannot get anything done because they are vastly outnumbered by the old fogies still writing policies like the 1950's.
Moreover, it takes more than one term to achieve any meaningful change. Things like Obamacare didn’t just start with Obama. Major changes takes 10+ years.
Congress/senators should be under better scrutiny, yes. Don’t let them become corrupt, prevent insider trading etc. but terms limits is not the solution to this problem. In my opinion I think term limit would rule out “poor people” from ever trying to run for office.
