Time to send in Senator Sanders.
Why? For what?
He campaigned pretty hard for Jacky Rosen in 2018, and I suppose you could argue that helped her victory. (Although you'd need some more data than I have to do so.)
He also whooped Biden there. Hispanics love Mr. Bernie!
The primary has very little bearing on the general election. Also, in the primary, younger Latinos favored Bernie but older Latinos favored Biden & Bloomberg.
As we all know - older voters are more reliable.
Where did older latinos ultimately favor Bloomberg over Sanders? Looking at the exits it seems Sanders carried or was at least highly competitive with older latinos in most of the states where there was a significant latino population (Florida being the obvious exception).
Anyway, Biden should be trying his best to bring out sometimes unreliable voters too. They could make the difference in states that end up being close.
