You won’t really know until election day.
It's not over until the ballot booths all close.
And the votes are counted.
And all the major networks declare a different winner at least three times.
And everyone gets befuddled.
And both acceptance speeches are cancelled and everyone goes home and a recount is demanded for an entire state and the protests rage and lawsuits fly and the candidates both pick cabinets and walk around all Presidential-like and commissions are established and counting methods are argued and the State Supreme Court extends the re-count and the U.S. Supreme Court vacates that decision and Larry King interviews EVERYBODY without asking a single real question and the counts conclude but the Election Czar refuses to accept some Counties' because they've passed the deadline and it’s getting on toward Christmas/Hanukah/Kwanzaa/Winter Solstice and the State Supreme Court allows a RE-RE-count and the U.S. Supreme Court "remands" and everyone figures out that it really just means the Federal Bench just threw the whole issue out with yesterday’s newspaper.
And then tomorrow’s paper names the new President.
Polls really mean nothing.
