From what bench? Trump is such a paradigm changer that IMHO people will want someone like him, never to go back to a slip and fall lawyer like Schumer.
Sadly whoever follows PDJT will be like the next skater to follow Nathan Chen ( The young lad that is doing the Quad Jumps with record total scores ).
President Trump like Chen is in his own zone, a once in a life time talent.
Where the Dem's find someone like that, ya got me....
They just need to find the black/Hispanic/atheist/Muslim/woman/trans who is also acceptable to the rest of the black/Hispanic/atheist/Muslim/women/trans in the party. It won't be easy. When your model is race politics, and each group thinks it's their turn, closing that sale is a near-impossible job.
