(too long for most people to remember the answers they gave on tests)

For me at least, one year is also too long for me to reliably hold the same opinion, so if you did that to me, I think I'd likely say something like “Yeah, I did support X, Y and Z back then, but now I've changed my mind.” (I'm not one to cache opinions about most political issues -- I usually recompute them on the fly each time I need them.)
