Unfortunately, the tactic of not voting doesn't work either. The ruling class reads low voter turnout as complacency and they know that it is easier to steal from the complacent.

A high turnout warns the candidates that the people are watching.

Sadly some politicians actively work to suppress the vote.

If you watch the polls, you will see that pollsters pay as much attention to voter turn out as they do to voters opinions of the candidates.

More than one election has been won by campaigns designed to suppress voter turnout.

The Trump campaign didn't win just by making people love Trump. The Trump campaign set out to make Democratic voters stay home.

PS: The primary objective of negative campaigning is to make the support base of one's opposition stay home. By not voting, you are doing exactly what the people engaged in negative campaigns want.
