IMHO there are some rational reasons for a libertarian voter to support Bernie:
1. If elected, it would mark the first time a truly grassroots, crowd-funded candidate (in the same vein that Ron Paul was crowd-funded) is elected President. This would be a positive step for our democracy. And yes as a libertarian I recognize democracy is evil but the fake, corrupt democracy we have is even worse. We may need to reform democracy in this country before we can use democracy to reform and reduce the size of government.[/quote
2. Bernie would be the first candidate in a long time (or forever?) to be fueled in large part by a young constituency, which is famous for being politically uninvolved. This too would be good long term as the youth are more open-minded to liberty than the older generations.
Not sure how either of those things would help us...
If Bernie manages to win on small donations, how would that help us win on small donations?
If Bernie gets the youth to turn out for him, how would that help us get the youth to turn out for us?
3. Bernie seems very interested in un-corrupting our democratic process. I'm very skeptical he can actually move the needle on this, but if he's able to do this, it might help us down the road in getting an un-corrupt liberty candidate on the main debate stages.
Bernie would have no ability to influence how the GOP/media organizes the GOP debates.
He could influence the Democratic debate process, but I doubt he really would, and we're not running candidates in the Democratic Party anyway (and for good reason).
4. Without going through the laundry list, Bernie does have a lot of positions that are steps in the right direction for liberty
He's mildly anti-war and pro civil liberties. He's the very worst candidate on either side on economic issues.
...not nearly enough overlap to make me even consider voting for him.
5. He does target the banks, albeit not in the same way we do. More attention focused on banks-as-villains could help us in educating more Americans about the Fed.
I don't see any overlap at all on this front.
Being anti-bank, in the sense of wanting to nationalize them, has nothing to do with being pro-market.
Being anti-Fed, because you think it hasn't printed
enough money, has nothing to do with opposing central banking.
He's not educating people, he's leading them to a 'cure' for the banking problem that worse than the disease.
