There is some truth to that, but on the other hand how long does it take to figure it out? I see zero downside in having some sort of term limit, be it 2-4 terms. Alaska has had 4 representatives since statehood. One has served for 48 of the 58 years? At 86, do you think maybe he has had his fill?
That's up to the voters of Alaska to decide, isn't it?
It takes a long time to figure out how to govern well. It takes no time to learn how to demagogue and grandstand. What we have now is demagoguery & grandstanding, with precious little governing going on. The GOP spent 8 years of the Obama presidency obstructing the administration's goals. Democrats have done that the last 3 years of Trump.
