It wasn't just about domestic things but you're missing the point entirely in the first place, Democrats need to come together if we're going to beat the Republicans. Everything should revolve arouond, first and most utterly foremost, beating the Republicans. All differences need to be set aside immediately. Trump is a threat to national security and international stability, he's selling out to Putin, he's trying to extort the North Atlantic fucking Treaty Organization, he's facilitating an elite takeover of the United States federal government, as well as trying to defeat the move to block F-35s being sold to Turkey and private technology and intel falling into Russian hands. This whole "but she was Secretary of State" mind-set is just as harmful as "but her Emails!" "But Obama!"
And no, she was also First Lady, and this image might ring some bells...
