Elections can be confusing, especially in America. Seriously, just go ahead and try to explain the Electoral College to someone from another country and watch their face while you do it.
Heck, we even have a problem with getting our votes properly completed in the USA. Remember the "dimpled chad" fiasco back in 2000? Thanks, Florida.
Given that the election process can be confusing even for adults, can you only imagine how difficult of a concept it is to grasp for children?
