I thought we lived in a democracy?

I am irate at the fact that my floor did not recieve enough votes to get 24 hour visitation. The system is flawed though. In order for it to be passed 85 percent of the floor has to vote yes for it to be passed. Just imagine if that was how we elected our president? We would never be able to get 85 percent of Americans to vote let alone vote for the same person. I personally voted so I feel robbed that we did not recieve it. Oh well, thats life.
