Free will

 We have free will if our choices cannot be calculated ahead of time. If the universe is uncountably infinite then perforce we have free will. This can be seen because calculated means there exists a Turing machine that produces the desired result. A Turing machine cannot calculate the uncountable infinite because there is at most a countably finite number of Turing machines. 

i heard someone say vote to make your voice heard

 Let's look at the design of the system from an information theoretic perspective. Say there are N candidates. My vote will be to select one of them. How many bits of information are in that. log base-2 of N bits. So if there are 4 candidates, my vote would be 2 bits of information. That is the loudness of my voice when I vote. Two bits of information. If I were speaking English, I could not say a single word without exceeding two bits of information.
