To have more rational, not emotional voices, in the House elect more Republicans.
Out of curiosity, who would those rational non-emotional voices be attached to?
As it happens, mostly to people who have exited the Republican Party, some of whom are now counseling OTHER former Republicans to vote Democrat and thus destroy the current Republican Party in order to pave the way for their eventual return...maybe in a generation if we don't screw things up.
The only people pushing the Athenian Straw Man Nonexistent Threat of Slippery Slope Windyfoggery (ASMNSSW) RE DEMOCRACY are people who have a misunderstanding/problem or hatred of democracy. (See AUTHORITARIANS)
