I actually remember reading this interview about Defending the Undefendable in which Block said this about voting
About the elections in U.S.A. What’s the right strategy for Walter Block? No vote? A vote for the libertarian party? Or a vote for the libertarian-wing of the GOP?
I advocate voting for the Libertarian Party. I would do so myself were I to vote, but I’m much too lazy to do any such thing. Also, juries are selected on the basis of voting, so that is another reason for people such as myself, who like to write a lot, not to vote.
The only member of the Republican party I am aware of who is a libertarian is Ron Paul, representative from Texas (and former LP presidential candidate). Otherwise the GOP is a wasteland, from a liberty point of view. As to the LP, they aren’t perfect (e.g., every candidate doesn’t always agree with me on everything – I’m just kidding). But by and large they have remained true to libertarianism, and I am very pleased with them. I speak at LP functions, and donate money to them.
