I almost never endorse politicians. I generally regard all elected officials, from the President to dogcatchers, as employees of the real ruling class (C. Wrights Mills’ “power elite”). Voting is merely participating in the king’s coronation rituals in a way that conveys legitimacy on the state. However, there are times when political campaigns can be used for propagandistic purposes. Ron Paul’s presidential campaigns in 2008 and 2012 are examples, and Tulsi Gabbard’s present campaign is another potential example.
I doubt she will get the nomination. The Democrapic party will either find a way to block that from happening (i.e. cheating), or she will simply fail to do well in the primaries because, in my experience, most of the kinds of people who are likely to be voters in the Democratic primaries are not people who consider foreign policy to be a primary issue. What passes for “the Left” in the US is, with some exceptions, pathetic when it comes to international relations. They’re far more interested in idpol, expanding the welfare state, and environmentalism (i.e. advancing the interests of the left-wing of the First World middle class). However, a Tulsi vs. Trump contest in 2020 would be a highly interesting turn of events for a range of reasons.
I think she would actually do better in a general election than in the primaries, though I don’t know if she could beat Trump or not. I think not because not only are there the standard issues like incumbent’s advantage but also because, given her views on international relations, the overlord class would pour money into the Republicans to keep Tulsi out of the White House, and the media would work overtime to ensure her defeat. Notice the only time the media (other than FOX) ever said anything good about Trump were the two times he attacked Syria. It would be a highly interesting and comical situation because the political class, capitalist class, deep state, media, etc would suddenly rally behind Trump after years of endless hating on him because they would view him as objectionable though more easily contained and less immediately threatening to the empire’s interests. It would be a true “memory hole” moment. Such a situation would also greatly exacerbate the cleavage between neoliberals (most of whom would move to Trump) and progressives (most of whom would stay with Tulsi). Certain dividing lines would become clearer among the center (radical center vs. establishment center) and right (neocons vs nativists vs populists vs non-interventionists) as well.
Of course, even if she won Gabbard would be constrained by the wider ruling class, political, and deep state apparatus. At best, she would be another Jimmy Carter, i.e. a moderate who is a generally decent person but essentially unable to maneuver within the framework of a system of overwhelming opposition by elites. The “Trump hate” that has been piled on by the wider ruling class is nothing compared to the “Tulsi hate” that would come about if she were elected (the same would be true of a Republican with similar views).
Any US president who seriously moved against the interests of the oligarchy would meet the same fate as Mosadegh, Arben, Suharto, Diem, Sihanouk, Allende, Saddam, Qaddafi, so many others.
