Like a lot of people, my first experience of democracy was our mock vote in first grade for governor of Pennsylvania, complete with cigar box and squares of lined paper. (Dick Thornburgh was running against some guy named...Flaherty? Flannery?) I hope Miss Cramer's happy that the lesson stuck. The church I was brought up in--if I haven't mentioned this--frowned on voting in national elections. God has plans for the United States and the world, see, and you could be voting against Him.
Just imagine trying to explain your way out of that one on Judgment Day.
Polls are often wrong, but if they're right, I won't be happy with the results today. That's the way these things go. Both viable presidential tickets well and truly bit this year, but fortunately, Washington is not largely controlled by the president alone, and the states are not largely controlled by Washington alone. Whoever wins is unlikely to wreck the republic. It just remains to see who it is.

Given the lines I saw, I think the predictions that this would be a historic voter turnout may be proven true. It was quite a sight to see.
Hey, you are an optimist :-)
I hope you are right.
