So this happened at a Beto campaign HQ a few nights ago in Austin. 
Here's another pig head sign placed in Austin, targeting both Cruz and Beto.
Red Guards Austin website: "An action was taken on behalf of the boycott of the bourgeois elections. Militants placed severed pigs heads and placards protesting the elections at polling places and campaign offices in and around Austin. We received the following photographs."
It reminds me of when Vladimir Lenin and his friends bought a pig head at a grocery store and quietly left it in one of Tsar Nicholas' parking lots in the dead of night to kick off the February Revolution.
