TAC has a “symposium” of multiple writers discussing whom they plan to vote for. Some endorse voting for one of the major party candidates and some endorse not voting, but several endorse third party votes or write-ins. Some of the writers include Andrew Bacevich, Justin Raimondo, Paul Gottfried and friend of this website Sean Scallon.
Daniel Larison has a separate endorsement here that wasn’t included in the symposium for some reason.
Samuel Goldman has a separate endorsement here because Hurricane Sandy precluded his participation in the symposium.
Here is a summary of the endorsements.
Romney — 4 (Coombs, Pinkerton, Tippins, Zmirak, Antle and Birzer leaning)
Obama — 4 (Bacevich, Hadar, McConnell, Millman, Giraldi in a pinch)
Goode — 1 (Scallon, Brimelow and Gottfried would if they could)
Rand Paul — 1 (McCarthy)
Hapsburg Monarch — 1 (Lind)
Not voting/ambivalent/unclear — 7 (Dreher, Dougherty, Gordon, Murphy, Raimondo [rooting for Obama], Richman, Russello, Beer, Sailer)
