The more charismatic candidate always wins. The Dems must pick a bigger "personality" than Trump (almost impossible) to beat him. If Sanders is still healthy he has to run.
Not totally incorrect, but I believe the Trumpster is not impossible to beat. Especially if he handles the presidency poorly and/or a recession occurs. A “bigger personality” is currently not there as I see it. The only ones I think of in this category are FDR, JFK, LBJ or Obama. But they’re either dead or term-limited. My hope is on Kamala Harris.
