Nope... wouldn't vote for him against Obama. While I like many of the things Libertarians stand for... I disagree with their Sink or Swim attitude when it comes to social programs.
Could I see a day, if all the Corporate Welfare, War mongering and Money out of Politics came to pass... a day where people...even relatively unskilled people who work for others get paid in a manner that can support a family and leave a little breathing room for savings and/or a small luxury here and there...that I would vote Libertarian? Absolutely.
This is frustrating to hear, because that's pretty much Paul's attitude in a nutshell. You look at his initiatives, the things he's actually promoting - he's all about getting rid of the warfare state and crony capitalism
before we worry about welfare. This is why I find the close association with Tea Party Republicans as damaging to the libertarian cause as it is helpful, maybe more so. Many of them tout libertarian ideals as a cover for the standard 'stingy Republican' mindset. But that's not what Ron Paul, or real libertarianism is about.
The thing that gets Paul in trouble is that he always defends his ideals. So when pressed on his views on the welfare state, he'll tell you he thinks that it is
ultimately more destructive then helpful. But despite his strong, consistent ideology, he's not an ideologue. He has repeatedly called for cutting military spending so we can afford to take care of people here at home. And while, as a libertarian, he'd ultimately like to see as few people as possible dependent on the state, he has no agenda to see people starving in the street. Quite the opposite. He wants to end the culture of dependency that has been carefully inculcated by the corporate class to keep the rest of dependent and obedient.
