Democrats are a formal fallacy because they are unsound due to their structure and the Republicans are an informal fallacy due to their content making them unsound.
Definition
A false dilemma is an informal fallacy based on a premise that erroneously limits what options are available.[1][2][3] In its most simple form, called the fallacy of bifurcation, all but two alternatives are excluded. A fallacy is an argument, i.e. a series of premises together with a conclusion, that is unsound, i.e. not both valid and true. Fallacies are usually divided into formal and informal fallacies. Formal fallacies are unsound because of their structure, while informal fallacies are unsound because of their content.[3][4][1][5] The problematic content in the case of the false dilemma has the form of a disjunctive claim: it asserts that one among a number of alternatives must be true. This disjunction is problematic because it oversimplifies the choice by excluding viable alternatives.[1] Sometimes a distinction is made between a false dilemma and a false dichotomy. On this view, the term “false dichotomy” refers to the false disjunctive claim while the term “false dilemma” refers not just to this claim but to the argument based on this claim.[1]
So are you picking Harris not because she will not do the same things but because she would do the same things but in a slower fashion and also just to show that we have no other options?
not sure that would classify as a democracy are you trying to enforce the elite’s false dichotomy?
