This only underlines but long-expressed demand that the Electoral College exit off the undemocratic stage. Voters in the vast majority of states apparently get it--their vote is meaningless in prez elections.
Competitive states generally turn out voters at slightly higher rates than noncompetitive ones. But as the list of swing states narrows, and as the campaigns become increasingly effective at aiming their resources toward them, the discrepancies may widen in the coming years. Americans outside the battleground states, knowing that their votes will make little difference in the Electoral College, may become less likely to vote at all.
