These folks were VERY eccentric. To put it politely.
Lots of Libertarian bashing going on in this election post-mortem. Lots of people trying to blame Libertarians for this debacle.
I've never understood the assumption that every last Libertarian would have shaved their beards, put down their bongs and voted for McCain had a Libertarian candidate not been on the ticket.
As you said, many of them are eccentric. I know a few of them and they're not wayward Republicans. They have as much contempt for the Social Conservatives as they do the Big-Government Left. Very few "true" Libertarians would've voted Republican. It is foolish to add Barr's numbers to McCain's and wonder what could have been.
You're probably right.
I don't know what it would've taken for Libertarians to have gotten the picture - the picture that with Obama and his totalitarian puppetmasters in charge, their precious liberties will be taken away.
Except for legalized drugs, of course.
You can stop the libel any time you want...
