There’s a lot of good reasons to impeach Donald Trump. Let’s start with the fact that he is an asshole. Rude, crude, socially unacceptable. Openly talks in racist language. Coddles Nazis. But in their impeachment inquiry Democrats are instead focusing on a very hard to follow narrative about his phone call to the president of Ukraine, in which he asked that country to investigate Hunter Biden, the son of vice president Joe Biden, and initially threatened to withhold military aid but then granted it. This is way too much like Iran Contra: who can follow the story even if it’s true?
