One clear historical example people have to keep in mind is June 2014, when Labor won the Presidency by five votes over a TPP/DR ticket, with 11 out of 40 Federalist Voters casting votes for the Laborite to be President (we didn't have anyone available to run, RL is a pain sometimes). That was one time Labor a dash for populist right and not libertarians (makes sense since the other ticket had a libertarian on it). One month later they put one of their most extreme members in charge of the Senate and nearly passed a bill nationalizing power companies. Needless to say those 11 Federalists regretted their votes. Labor was devastated in the August midterm elections, putting a coalition of Feds, DRs, and TPPers in charge of the Senate.
Weirdly enough, I was one of those 11. I don't recall
why I voted the way I did, but I remember that Sirnick was pretty pissed at me and wouldn't drop the subject for quite a while.
