“There are no formal political parties and election campaigns are largely based on personal/family ties and reputations.”

Parties and partisanship get a lot of crap from self-righteous idiots on both sides of the political spectrum. They are a natural feature of democracy, and when one of the parties wants to outright destroy the country, “hyper-partisanship” is only reasonable course. How do you “work together” when you want opposite things? You don’t. Lions and gazelles don’t work together. Muggers and little old ladies don’t work together.
We need an “Era of bad feelings” to grind the enemy into dust.
I'd say we're there about now.
