The only reason I would vote 3rd party is if Gabbard gets the nomination. She’s on the right politically. Trump is far right.
But centrist/corporate Democrats are also on the right politically, because they serve their donors and not the American people. So, why would you vote for that? Any Blue won't do, when it isn't really Blue. Haven't the right-wing Clinton and Obama presidencies taught people anything? Identity politics doesn't make you left-wing, it's the economic policies. When these serve concentrated wealth, they are right-wing. Leftism has ceased to exist in the USA after Jimmy Carter. Only Sanders can bring it back.
This in turn means that any strong country can now invade another weaker country, and nobody would do anything about it.
You mean like invading Vietnam, Iraq, Afghanistan, Libya, Somalia, Haiti, Panama, and so on, never mind helping all the overturning of democratically elected governments all around the world? Please, take your exceptional-USA, war-mongering attitude elsewhere.
Enough about the isolationism BS. The US stopping its regime-change wars for corporate profit has nothing whatsoever to do with isolationism. And to call someone who wants to end these wars a 'right winger', just shows how topsy turvy things have become in the USA. And that's because hardly anyone takes a stance based on principles, but only on tribal divisions.
I'm not a great fan of Gabbard's, but if I were American, I would welcome her stance on regime-change wars, so that it becomes something that can be talked about, just like Sanders pushed the Overton window on medicare4all. Because the US has to stop influencing/invading other countries for corporate profit (sorry, Rob).
