I always wanted to ask this question on how in the U.S.A. they work out who wins the race for the president.
1) Can every American that's over adult age vote? (Not those in prison).
2) Do they add up all the votes and who gets the most gets in?
3) How much money does it cost to run for President.
I ask this as in United Kingdom, the whole are is split into areas where M.P.'s from different Party's get votes, when they win a seat in that area they represent that constituency.
When they finish the election, the party with the most seats gets into power.
I say this as thinking about your last election AL Gore V GW Bush jnr there was a big thing about certain minorities not getting the vote and service people overseas also not having their votes counting, the news reported that it was like a difference of 600 votes, if my memory serves.
If that was the case for the U.K. that we had a vote tally rather than seats Blair would never be Priminister of the UK, ever. Labour got more seats but they got less votes.
As for people changing their minds, it's a show of maturity if they can stand up and say they got it wrong and will put it right.
