This is the wing of the party that focused on losing issues like abortion and whining about muh diversity**
No, they didn't. Clinton spent her time basically attacking trump as abhorrent (and she did say things about policy, which the media never bothered to cover because hyper-focusing on her attacks on trump and emails was better for ratings), and it likely would have worked if it wasn't for the FBI letter and its convenient release date. Plus, abortion isn't a
losing issue, its what makes pro-choice voters choose democrats, but it isn't a good thing to base a campaign entirely around, as you only need to say a certain amount about it to energize the base and after that it really doesn't do much but make you seem like a joke.
