This works because almost all the US uses first-past-the-post elections for the Presidential general election. So you get outcomes like this:
Scenario 1:
Biden: 10 votes
Trump: 9 votes
Kennedy/Stein/West: 0 votes
Biden wins the state
Scenario 2:
Biden: 9 votes
Trump: 9 votes
Kennedy/Stein/West: 1 vote
Tied vote, decided by game of chance/lawsuit
Scenario 3:
Biden: 8 votes
Trump: 9 votes
Kennedy/Stein/West: 2 votes
Trump wins the state
This is why you see huge financial support from Republican billionaires for third party candidates who have no chance of winning.
They’re going after formerly reliable Republican votes that have had enough of Trump but don’t really want to vote for Biden.
Those are very reliable voters and they don’t want them staying home or voting for Biden. So they give them a shitty third-party candidate so they won’t vote for Biden and still show up for the down ballot Republicans. Might take a few potential votes from Biden but that’s only half the goal.
Yeah but he’s as fringe as trump just in different ways. Plus it’s the opposite of what they think will happen with the dem vote. Republicans who would otherwise vote Biden or stay home will hear Kennedy and think liberal. But near 0 dems will fall for the same trick.
People who are paying attention to the news, sure. But a lot of people don’t. And that’s who they’re trying to reach. So it’s important to tell people what’s going on.
