Those CR ratings are good, they must have some sort of system that grades the legislators BUT, some at the top of the ratings, Paul, Lee and yes, Thomas Massie have had some questionable votes. Remember, Paul and Lee voted against the wall, whatever that motion was, maybe against the declared emergency, emergency funding, however that would be described.
So, those ratings to me do not mean, this guy is going to vote the right way. Those ratings are of limited use but nonetheless, handy, like those freedom ratings I've posted for countries, the equation is not perfect but it gives one a general idea.
