I've been working away on the people at my work over the past couple of months.
Good few already Yes but so far I've managed to get 3 undecideds over the line, 1 No to Yes by encouraging more research and only last night one extremely staunch No as little as 5 days ago (NI born, history in the forces) completely surprised me by telling me he'd read the WBB I've left lying around work, spoke to his wife, did more research and him (and coincidentally his wife too) are now both Yes. I honestly thought he was taking the pish when he told me this. I had written him off and I had to ask him more than once, as shocked as I was.
Also managed to get a few friends converted via Facebook postings of articles which again encouraged them to read into things more, so I can believe the article saying more research encouraged a Yes vote, from my own experiences.
This is here to be won.
