Gary Johnson is going to pull in the Sanders supporters.
This will help Trump a lot.
However, there is only one party for conservatives:
The Constitution Party.
Are you casting an anti-Clinton vote, rather than a pro-Trump vote?
With Sanders voters going to Gary Johnson, perhaps you can afford to vote like a true conservative AND not support Clinton AND send a message to the GOP that it cannot ignore its conservative base.
Consider voting for the Constitution Party.
