Fuzzy Bear would win easily, but I'd probably vote for fhtagn.
No the Republican Establishment would no doubt will go all in for Fhtagn than support someone who supports Bernie Sanders Social Security Plan and is pretty liberal on economic issues.
Trump was able to get around that due to these reasons
- He had a massive amount of name recognition
- He faced a super divided Republican field
- The GOP establishment went all in for literally the wrong guy(Jeb Bush)
- He got 2 billion in free media
He can still win but it would be super close but I would give Fhtagn the edge.
