Agree.  Recycling Warren, Chelsea Clinton, Waters for a 2020 presidential run will almost guarantee a Republican win, even if Trump is not impeached before 2020.  These Democratic retreads have way too much baggage in the eyes of the electoral vote college voters & will be a repeat of the Demos losing again in 2020.  the exception might be Kamala Harris, even Tulsi who is considered a military veteran, but the best chance for the Demos is a male military veteran with no skeletons in the closest, who like Obama is half Caucasian & half black but looks more Caucasian might be what the Demos need to take back the Whitehouse.   After 8 years of Obama, right now it is somewhat of a racial thing for a candidate to win the electoral college to become President of the US. Trumps policy of cracking down on illegal immigrants in the US only will strengthen this trend of maintaining white in the Whitehouse.  Maybe Kamala Harris can lighten her skin color like Beyonce & listen to country music.
