I believe the DNC will go with a stable and moderate candidate for 2020, one who can energize the Dem base, reach across party lines and still placate the far left. The candidate is US military veteran, H.I. Representative Tulsi Gabbard (D).
The following bullet points aren‘t my own. Instead they come from an article I came across laying out a great case for her candidacy. Although I‘m fairly certain I‘m voting Trump in 2020, if Tulsi Gabbard was on the ticket she‘d most likely earn my vote.
