Re: Compulsory voting in a federal election.
Np, anytime

As we're on the subject, I think it's important to point out that, the Presidential/Vice Presidential election in America is far from Democratic.
1. The general population does not actually vote for the Pres/Vice Pres, they vote for a representative of the Electoral College (an elector)
a. Each state is given a certain amt. of electors (equaling the total number of representatives that the state has in congress, meaning, their senators (2) + their members of the house of representatives (at least 1) )
b. The number of votes that each state is not proportional to the populations, meaning that a vote in a smaller state is worth more than a vote in a larger state
2. The electors have the ability to change their vote at any time (even once the voting has begun), meaning that, an elector may change his/her vote at the last second, meaning that anyone that voted for that elector has essentially changed their vote.
3. The "Winner-Take-All" policy that is enforced in 48/50 states means that the presidential election is not really 1 election but rather many individual elections then 1 major election based on those individual election (the "winner take all" policy is the policy that states that, once the votes have been tallied for a state which uses this policy, the candidate which received the most votes wins ALL of the electoral votes.
a. This means that, if you are in a state enforcing this policy and you vote for a candidate which does not end up being the majority in that state, your vote essentially does not matter anymore.
b. This also means that larger states matter more to the candidates than the smaller states (as they have more electoral votes and matter more in the election)
So, in the end: the Presidential elections are very confusing and non-democratic, no matter how democratic they appear to be.
