GOP voters, by and large, can't be bothered to amp up for every election. This is why the DEMs keep re-surging when they appeared to have been buried. They have a solid group of rabid voters (alog with a well-entrenched voter fraud system) who seek change at the polls.

NYC has 6.5 million voters (thereabouts) but only approx 2 million showed up to vote this election. In the last four mayoral elections, fewer than a third of registered voters could be bothered to vote.
