Political parties are probably necessary. I am not a member of any of them. I have, in the past, been a member of the Democratic Party and the Libertarian Party. Neither really were a good fit and I have no desire to formalize a relationship with the Republicans although they are more likely to reflect my beliefs, at least superficially, than the others. Where they lose me is when they take the advice of liberals who tell them where they are going wrong and how they will be more successful by adopting lukewarm versions of Democrat policies. Like that will work. I prefer a sharper contrast.
I rather like that. In fact, I think congress should be appointed by lottery. Senate, too. Even the executive. If you served in the military or on a jury, you're in the lottery.
