VP choice makes a bigger difference for an older candidate, which might be why rumors are that Biden will be choosing his running mate very early in the process.
Unless the nominee is Harris or another woman. Then a white male would be a smart strategic move to play to middle of the country demographics, which cost the dems the 2016 election. Buttieg, as an Indianian, among other characteristics would be a perfect fit.
My hunch is part of his strategy is to make a strong showing in order to be the VP candidate for a non white male nominee.
We need to take bets on when Texas turns blue in a Presidential election, I bet 30 years in the future, 2020 is too soon. Beto did great against the least popular Senator in the United States. The voter registration number among Latinos in Texas is abysmal, but they will be a bigger bloc than any other in Texas in the future, it's just that older, whites make up 2/3 of Texas voters now and that's a pretty reliable GOP vote source.
Every year for some time people have been saying Texas will turn and it has not happened.
Almost nobody really makes their voting decision based on who the VP is. I'd even have to look up the name of Clinton's running mate from the last election.
