Scott won because he’s the outsider. McCollum was the establishment-backed candidate. And the Florida GOP voters want nothing to do with the state GOP. The voters did the same thing by rejecting Charlie Crist and backing Rubio. The Florida GOP establishment has lost control. They are facing a revolt from their own voters.
Same thing is happening right now in Delaware. The voters would rather lose the election than allow a RINO or an establishment candidate to win. Voters now want outsiders and a new kind of politician than these career guys.
Speaking as a Republican in FL, you are 100% spot-on correct. I am SO sick of the GOP "establishment" here, I could puke.
