Probably? What does that mean? Either they are tied or they are not.
Anyway I really think that this is to good to be true in any case.
Huckabee would win some states by gigantic margins while Obama would win enough states by not-so-gigantic margins. Huckabee wins the cultural South except perhaps Virginia and Florida while Obama holds onto the Blue Firewall -- likely by smaller margins than in 2008. With a 50-50 election Obama wins basically Gore2000 + NH + NV+ CO (probably just short of 270 electoral votes) and one of Arizona, Florida, Montana, Ohio, either Dakota, and Virginia... barely. That Huckabee wins some Southern states by margins near 40% means nothing if he can't cut deep into the Blue Firewall.
That's if the election were held today. But there won't be any snap election, Obama is not in campaign mode (where he excels), and his political machine is still in mothballs.
