The guy has never worked an honest day's labor in his life! He's a life-long political hack that has been trying to gut medicaid, medicare, and social security for 40 years.
Not that your vote will matter in the least, since the democratic party is under absolutely no obligation to pay any heed whatever to whomever the democratic primary voters choose as their candidate. They will meet in their back rooms and choose whoever they think won't upset the Big Gravy Train (that will likely be Biden) and then they'll get on with their corrupt business as usual regardless of whether Biden or Trump wins. If Biden wins their bribe packets will increase, but their risk of being bounced out of office next election cycle increases, too. Whereas if Trump wins they'll keep on taking the current bribe amounts, and keep voting however their corporate sponsored lobbyists tell them to vote, and then they'll blame it all on Trump next election cycle. And we'll believe them, because we are idiots, and re-elect them.
