He might be slightly biased since he's an Englishman but, as he points out, "The anti-independence side actually has some legitimate arguments to make. Leaving the UK could potentially have some serious consequences for Scotland." Chief among other concerns, the economic unknowns are scary and will almost certainly have global repercussions; even Alex Salmond, the lead politician pushing for independence, didn't have an answer when asked at a recent debate what currency Scotland would use if his party succeeds.
From everything I've read, it sounds like Scottish independence would be a disaster even more for the Scots than for the remainder of the United Kingdom, which would then be comprised of just England, Wales, and Northern Ireland. Of course, as an American I'm not really allowed a say, but we do plan on moving back to England in the future and Jon's family is originally Scottish so I do feel somewhat affected regardless. (Plus, because Jon and I are trying to merge our bank accounts now that his visa has been granted, we're directly impacted by the volatility of the pound as the market reflects the uncertainty of the outcome of the vote! This is one time I really would prefer sterling to be strong against the dollar.) The referendum is too close to call at the moment - if you're interested in following along, make sure to check #indyref and #scotlanddecides on Twitter. It's going to be an interesting few days for British politics!
