The Incumbent is dealing with several challengers - much like the primary for the Dems, the Republican field is looking a bit crowded right now, too.
At the moment, competing for the Republican Nomination in 2020 is:
* Bill Weld
* Joe Walsh
* Rocky De La Feunte
* [You know the Drill.]

There seems to rising support now for the other challengers/contenders, chiefly due to the incumbent going through an impeachment trial currently.
