The "base" are the ones who ALWAYS VOTE and who are LOYAL to the Democratic party, and Democratic candidates. They also register as Democrats, they volunteer, they hit the pavement, the canvas, they call, and they donate.

There is a common misconception that "base" is another way of describing the most-pure and most-left liberals. That's simply not true.

Sadly, the voters who are furthest left often sit-out elections for various reasons... and when people don't vote for the Democrat... when people don't support the Democratic party, well... that just makes it easier for the GOP to steal elections.
