@ChrisHolladay yep, it seems to mean... Nothing. Did he registered as a republican just to vote against Trump in a primary? Because he was a fan of Lincoln? Did he do it on a dare?

I read he'd made a single political donation to a group on the left, but it was $15, so hard to get anything meaningful from that either.

But, I am confident confirmation bias will continue to help people solidify their existing opinions.
