People talk about it all the time. Ron Paul was a household name. People we're talking about RFK JR a year ago. People were talking about 3rd parties due to Biden's stance on Palestine. People were talking about it after that first debate. All that's fine, but it only makes the two main parties sweat within 30 days of election. That's when all the "throwing your vote away" rhetoric ramps up.
Rather than doing better, working harder, or standing on better policy to turn out the 35% of people who don't vote, it's easier to vilify 1% of the people who do. That's a problem.
