Possible Republican candidates are scrambling to succeed House Speaker Paul Ryan in Congress. Some likely candidates include former Republican National Committee Chairman Reince Priebus and Assembly Speaker Robin Vos. Another name being brought up is University of Wisconsin System Regent Bryan Steel, who is a member of a powerful Janesville political family with close ties to Ryan. Political analysts are considering the once Republican stronghold a toss-up race. Ryan says he won’t endorse a candidate in the G-O-P primary.
