It’s enough to make one think that the ACLU isn’t really a good guide for what qualifies as “libertarian”.
There are actual reasons why both of the Pauls are Republicans, not Libertarians.
I would argue that Ron is definitely “more libertarian” than Rand.
Then again, anyone who espouses a smaller, more Constitutional role for the FedGov is aligning with libertarian philosophy whether they are cognizant of the idea or not.
The ACLU has been a Leftist parody of what it could have been.
