The only thing I know about Beto is he loves to use the F word in public, in his campaign rally’s and interviews. That may play well in the liberal communities and college campuses but it is a huge turn off for average Texans.
In addition to that, Beto comes across as a smarmy wanker. Also, he looks like a textbook Beta - the dude aspires to be big enough to wear skinny jeans. Add to that the fact that he is the product of a corrupt family, and is your average Progressive.
