No. The absolute largest chunk of people considering changing their votes at the moment are disappointed non-conservatives. There was barely any competition among republicans; from the get-go, the voter base united behind Trump. If non-conservatives split their votes across multiple fronts, they WILL lose.
Voting third party in America throws your vote directly into the garbage. Our system does not work like Australia’s. You don’t get a second or third choice, and candidates who win aren’t going to look at the numbers and say “I see 25% of Americans voted Green, I should implement Green policies.” That’s not how it works. Conservative voters overwhelmingly back a single party, the GOP, while non-conservative voters are the ones that scatter across multiple, weak fronts when faced with an unappealing Democratic party nominee. Think about it like this:
The majority of Republican voters support Trump and are not changing their vote even though party leaders and figureheads are universally decrying him. They’ve been groomed for decades by the GOP to be this way, and now party leaders have lost control of the impressionable voter base they created for themselves. There’s nothing they can do about it at this point. While a small number of Republicans can and are switching parties, it’s not very much. Meanwhile, Democrats are floundering, trying to decide which front to unite under. Some of them go to the Green party or Libertarians, sure; the rest stay with the Democratic party in the hopes that even with people leaving, they will have enough to block Trump. But Trump doesn’t need a majority of total Americans to vote for him; he only needs more than the other candidates have. Do you understand what I’m saying? Trump could get 10% of the vote, but as long as no other party has more than 10%, he still wins. The second you split the left and middle across three or four fronts, the right seizes control. This is how it goes down every single fucking time we go through this.
The other thing to consider is that the electoral college is NOT going to weigh in favor of a third party. Doing so would be political suicide. They are paid to vote certain ways, and not doing so would fuck up their careers. Even if an entire state votes in favor of a third party, the electoral college is going to vote for whichever primary party matches up the closest, and sometimes not even that. Their votes are counted when making the actual choice of president; ours are not. They proved that with Gore. The majority of Americans voted for him; the electoral college installed Bush anyway and told us to suck it up. The question at this point is whether they’d risk it a second time, and we have to hope that they won’t, which is why we have to unite under a single front to block Trump.
