It's laughable that any Republican would think they can be re-elected. Some will, of course, but it will a long time, if it ever happens, before they can feel any degree of confidence.
They have too many enemies.
They've made enemies of their base, many of whom are walking away from politics at any level simply because they understand there is no point in pursuing resolution to the Country's or society's problems as long as unprincipled politicians inhabit public offices.
The Communists won, Republicans. You ensured their victory.
Now be honest enough to admit you never cared as long as you got yours.
