Supporters of one of the two old tired political parties often screech that if you don't vote for their candidate that your vote is wasted. This is a fallacy. In fact voting for the underdog often has more of an impact.
In the 2019 presidential election in New Jersey there was a 540K vote difference between the two. If you had chosen to vote for one of the two corrupt parties your vote would have changed that by 0.00018%. If you were to vote democrat it would have changed their total by 0.0000046%. If you were to vote republican it would have changed their total by 0.0000062%
While if you had voted Libertarian you would change the LP vote total by 0.00138%. A small number, but 222 times the impact of voting for the awful Republican and 295 times the impact of voting for the awful Democrat.
NJ is a winner take all state. If you want to make the biggest impact you are better off voting third party. If you were to spend your time driving to the polling location, waiting in line to cast a vote, why waste it on an unprincipled candidate?
Always vote for principle, though you may vote alone, and you may cherish the sweetest reflection that your vote is never lost. John Quincy Adams
