50/50 I done something similar at school to determine which political party my thoughts were closest to at the time and I'm sure it was right down the middle as well which said Lib Dems.never voted for them right enough.
55%left 45%right, a left leaning centrist. Probably about right I guess. In an independent Scotland that would be the way I would be thinking about voting. Still hate that ratio after Indyref tho!!! :-(
