Some Political Scientists Argue That, for Most Americans, Their Vote

Some political scientists argue that, for most Americans, their vote for president doesn't really matter. What is the strongest reason for this belief?

A) Since most of the states are "winner-takes-all", your vote only matters if you live in a swing state.
B) Electoral College electors so frequently ignore the wishes of the voters that it's as if your vote doesn't matter.
C) Each presidential candidate is going to do the same thing in office, so it doesn't matter who wins the election.
D) Most years the president is actually selected by Congress because there is no majority in the Electoral College.
E) It is hardly ever the case that a presidential election is close enough for votes to actually matter.
