Well, maybe not yet.  But they ARE an indicator, there's absolutely no doubt about that.

Thing is, I'm afraid too many repubs (as well as other Trump 2020 voters) might become overconfident in these numbers and think they don't have to show up to vote because "he already has lots of voters in his corner".  Maybe so, but we should NEVER assume anything.  NEVER. 

Git yer ass out there and vote when the time comes in November.  Don't get complacent.  PLEASE PLEASE DON'T GET COMPLACENT.
