Beto loses for governor of Texas, I anticipate Biden drawing him into his administration to get some international experience. It will get him national exposure, and get him in the highly successful Biden Administration. With the best economy in the history of the USA, Beto can ride on Wrecking Ball Joe's coattails.
Then he can go back to Texas and run again for senator, or whatever. There will be a strong effort to displace Cornyn, the anti 2nd amendment rat f*** that has betrayed every American. And just maybe, Beto boy with his wealth of Washington experience will beat whoever champions traitor Cornyn.
