Gary Johnson is sort of a left leaning liberterian. So, he will likely pull a few more votes from Trump than from Clinton, but will pull some from both.
If there is a Green candidate on the ballot, they might pull a few votes from Clinton.
It’s remarkable how little traction Jill Stein is getting, considering the Democrats just nominated a corporate shill who wants to militarize the entire Middle East and probably attack Russia.
I resent the establishment republicans who will not support Trump. They cannot see the bigger picture. The future Supreme Court appointments are enough reason not to vote for Mrs. Bill Clinton.
