I would urge anyone whose uses tweets as a basis for decisions on who or what to vote for, to not do so. The same is true for campaign ads on YT and other social media platforms, or on cable TV channels, or on billboards or campaign mailers.

If you're going to vote, be responsible and do a diligent background check on the candidates and measures in your district. Check their funding sources (opensecrets). Check their voting history, if they're an incumbent. See what donors and PACs they owe loyalty to. Yes, it takes a little time, and you may have to deal with Google or other search engines presenting biased results, but then at least you have some idea what you're really voting for.

However, I personally think these Congressmembers have very little real power or decision-making capability. They're lower down in the state-corporate hierarchy, with the actual Central Committee consisting of people like CEOs of the major defense contractors, investment banks and hedge funds, fossil fuel producers, technology and communications corporation, etc. The American government is essentially an oligarchic or plutocratic system, with politicians and bureaucrats acting as little more than middle managers.
