Most was probably the wrong word. Most vocal would have been a more accurate term.
Since I only trust politicians about as far as I can throw them and few have missed any meals, I don’t put them through a popularity contest to earn my vote. I believe that the exercise of political power will cause them to change their behavior regardless of what they think. They are all opportunist little worms and will wake up one morning with a certain devotion to the conservative cause when we make them do so.
They read tea leaves. They pay people to read tea leaves for them. They consult psychics, toss chicken bones, and every once in while they even go back to their districts. When they see conservatives winning, when they see liberals losing, when they see voters express disapproval, they modify their behavior. Voting for Democrats or staying at home has the opposite effect, so I don’t do it.
Until you are willing to hold out for statesmen, you will be left with mere politicians.
