There are times, when the choice we are given is to vote for a Rat or a RINO. Saying you hate both, and either directly has your self-interests at heart can be very true.
But that is still the choice, even though you wish you had the unicorn option, you don’t.
The Rat is always vote against you. The RINO is mostly vote against you. That is the choice you are presented with. You still vote for the RINO as the least worse of the two. The RINO still helps your cause sometimes.
Specifically, having one less Rat and one more RINO helps with judges and Supremes. Sticking one head in the sand wishing for a unicorn is defeatist.
California-born and Mexico-raised used car dealer Rocky DeLaFuenta is the sole alternative option to Gov Rick Scott... but he seems "quirky", shall we say? He ran for Florida Senate as a Democrat in 2016, lost, then ran for President in 2016 as a Reform Party (Perot) candidate, and founded his own American Delta Party, and lost... then ran for NYC mayor in 2017, and lost... and he is currently on the ballot in SEVEN different states for a Senate seat in 2018. Someone really really really wants to be in power!!
(Oh, and he has already filed to run for President in 2020, as a Democrat.)
The fact that there aren't better options is OUR fault. The FL Primary hasn't even taken place yet. Had ANY decent Right-side person come along, we would have a shot. Sadly, solidly-anti-Left Rep. Tom Rooney (House FL-17, strong on guns and more) and Pamela Bondi (attractive Trump loyalist and current FL Attorney General) both declined to run in the Primary.
