The crowd was paying rapt attention.
It was a group of 30-something liberals, most of whom raised a hand when I asked them if they had registered to vote.
"We have a Republican primary coming up in a few months. If you don't get out the vote, we will likely end up with Romney vs. Obama."
None of them liked that idea, finding themselves disatisfied with both options.
Liberals are likely to vote in favor of bringing home all the troops and ending the flow of government money to big corporations, but many haven't heard of any liberty candidates who support those positions.
Indeed, the liberals/progressives/Democrats you meet may have blinders when it comes to anyone associated with the Republican party, viewing them all as reincarnations of George W. Bush. With patience, you can point out how Obama's actions have been nearly identical to Bush's, and how the honest for-the-people liberty candidates would offer a wonderful change.
