Yeah, they don’t amount to much, half of them are lefties like Bill Maher and Noam Chomsky, and half of them are a mix of liberal and conservative.
I think their best year for president was when they were trying to defeat Reagan in 1980.
Libertarians are lefties and will have to either become conservative on social issues, or continue to run their own center left party.
America cannot give up conservatism or then it ceases to matter or have importance, it becomes just a mere geographical place where money issues are fought over by anti-tax liberals and pro-tax liberals.
Why do you think those two people have anything to do with libertarians or liberty leaning Republicans? Did either of them endorse Ron Paul? Who do you think they voted for in the general election?
You clearly don't like the liberty oriented folks that often vote Republican, which is your prerogative, but politically speaking why alienate them as voters? In order to win any candidate has to get a majority of the voters, and alienating voters who agree with you on many issues is not a path to winning elections.
