As much as I love the Libertarian ideal, and would like to see RP in the white house, until the country gets completely tired of democrats the libertarian ticket (and those repubs with similar beliefs like RP) will do nothing but take votes away from more popular conservatives and GUARANTEE Hillary's win.
Just like Ross Perot took votes from Bush 1 in 1992 costing him the election if Ron Paul doesn't realize that he's not popular enough amongst voters and pull out to throw his support behind another, more popular, GOP candidate then we might as well just be voting for the Dem nominee.
You have to vote for the candidate on your side who is more likely to win otherwise you will guarantee failure.
