The greatest election success of the libertarians was when they tried to stop Reagan from winning in 1980, it was the high point for them in national elections, their greatest showing.
Perhaps, but one of the reasons he did so poorly was because the old-line drug pusher Libertarians refused to back him, and their new Conservative members quickly left. I remember it well because by July 2008, I was so disgusted with the GOP-E and McCain that I was seriously considering the LP as an alternative to the GOP. I studied its platform and was paying attention to its convention and internal debates. When McCain brought Palin aboard in late August, I put the LP aside to work as hard as I could for her, but after McCain lost the election, I took another look and saw that the LP liberal wing had essentially run off the Conservatives. I still keep up with its doings, but quite frankly, the LP has reverted back to its old drug-legalization platform as a priority.
