Disclaimer: Nothing in the following entry should be construed as claiming the Democrats are equally as evil as the Republicans, and that therefore it does not matter who wins the 2020 election. Clearly, both stances are false. In the short term, there is significant value in unseating the Republicans from power as much as possible. However, it is also simultaneously true that the two sides have much in common, and this in and of itself both poses a threat and severely limits the ability of the system to self-correct using its own institutions (e.g. electoral politics).
One side wants to increase state power so they can use force to maintain the traditional white, male, capitalist hierarchy. The other side wants to increase state power so they can use government action to limit the worst abuses of capitalism, and in general to pursue a fool’s paradise of utopia via the crafting of the perfect set of regulations with which to (micro)manage everyone’s lives. The scenario recently posted here of a Democratic president using emergency powers to get what he or she wants (and the resultant precedent this would establish) is all-too-possible.
The two sides disagree strongly on how state power should be used, but they both agree that it should be not only used, but increased significantly. Any support for the Democrats must be given with eyes wide open and in full knowledge of this inconvenient fact. Both parties are enemies of liberty, and both should be seen as such.
