I believe that you are correct, 2018 purged the worthless RINOs from the HOR. Now everyone gets to see how batshit crazy the RATS are, and will vote in 2020 accordingly.
Dont forget that MOST of these RINOS we rid ourselves of rode in on the Tea Party wave and became RINOS very quickly after entering THE SWAMP!!!! Mia Love was one right off hand that became a HUGE disappointment!!! I have NO FAITH any longer on who we send to DC, we may have rid ourselves of RINOS however I wouldnt count on replacements NOT becoming RINOS shortly after entering DC!!! We NEED term limits it is the ONLY way to fix this corruption and K-Street payoffs, these BASTARDS will never vote for term limits and without them our republic will always be corrupt!!!
Hopefully you are right.
