they were elected in like 40 years ago, then made it their career to stay there. so yeah, they may have won an election recently, but being an incumbent and household name in the area gives them a pretty massive advantage over anyone new running against them sadly.
This is about Stein and age in general, but let me say that, for example, I don't fault Trump for being an absolute garbage person, statistically there will always be garbage people. It's his supporters I take issue with. Nobody should be voting in incompetent or dangerous candidates, and if they are in a position of power, the average person is to blame.
you don't fault trump for inciting an attempt to storm the capital, or the lies he's told to vets, or the attacks he's invited in minorities? there's a long ass list of things that you should very much fault him for.
I understand what you mean, but still. the blame can be on a lot of people, such as the voters, trump himself, and the massive power structure of the gop behind him that's been weaponizing voters for many many years.
