What is is the impact of voting?
In voting for the president, the way the area or state
(depending on population and representation in the Electoral
College) usually determines how the represenative in the electoral
college will vote for the president. But sometimes the rep. will go
against what his/her region voted for and just vote how they feel.
In which case voting did nothing. In voting for state reps and
senate and house reps voting counts if you really get into that
sort of thing.
