They are counting on the lemming vote .... that if people see that Hillary is in the lead people will want to vote for a ‘winner’.
There is some truth to this. Some people who are undecided until the last minute will vote for the candidate who appears will be the winner. People like voting for a winner because they then see themselves as on the winning side.
It’s odd but it is a thing.
This is absolutely a thing and it manifests itself in uninformed people who have no clue what the candidates are about, policies, positions, etc. They truly vote sheep-like for the perceived front-runner to feel like they are a part of it. Unfortunately, poll taxes and tests were ruled unconstitutional.
