I'll bet you a pint at the Eisteddfod that the Yes vote wins by at least 10%.
This and other reports suggest that the referrendum measure to give the Senedd law-making powers will pass by a two to one majority:- http://www.walesonline.co.uk/news/wales-news/2011/03/01/67-will-vote-yes-in-referendum-says-poll-91466-28252921/
Nigel Dix of True Wales is advising Yes campaigners not to begin celebrating yet , however, because:- Back in 1997 there were polls showing a clear lead to the Yes campaign in the final days before the vote, but in the end there was a Yes majority of only 0.6%. The fact that this is the best scenario that he can envisage with which to rally his supporters says a lot more about his confidence than anything else. BUT in a sense he is right...there is no room for complacency. AmeriCymru would like to take this opportunity to urge all it's members and supporters in Wales to turn out and vote 'Yes For Wales' tomorrow. For those of us who live elsewhere....email a friend back home and urge them to do the right thing
