One of the problems with publicizing the misdeeds of the Republicans is that "The Republicans" isn't a line on the ballot. Much of what congressional Republican leadership does cannot be hung around the necks of your particular representative or senator.
Scalise, however, is the Republican whip in the House. His job is to get Republican representatives to vote the way that leadership wants them to. He keeps his position partly because, although the Party is embarrassed by his addressing a white-supremacist group, he is somebody who the members like and who gets their votes.
It is perfectly fair, then, to ask in a LTE to your local paper: "Is Roskam's vote really going to be influenced by a man who said he was 'Like David Duke, but without his baggage'? If he isn't, he should say so."
(You, of course, would substitute the name of your -- or a nearby -- Republican congressman for "Roskam.")
Let's make each local representative own their party's racism.
