I'm blocked too - but it's not a blocked IP address, my IP is completely different to that I had last time (different ISP), and I've got a completely different operating system too, so it's not cookies.
I'm surprised anyone can vote - they've rigged it somehow - maybe restricted the IPs allowed to vote to the very high circing states?
Clearly they didn't like the result last time, and are making sure that this time they get the "right" result. I think it's almost comic that the media, faced with declining stats they just can't deny, are now putting it down to "those pesky foreigners" and trying to make it out to be a truly "American" thing to do. Actually, I quite like that, how many people do it because of spurious "medical" reasons which are now being made obvious to be false, because the "pesky foreigners" are obviously quite healthy, and in the case of Latin Americans, have a reputation for being red hot lovers. It also shows how much the cutters are on the back foot.
So, anyone on the debate boards, when the pros start trumpeting the result, let the world know how the result is being rigged - it's important!
