Joe Biden has an inconsistent voting record

The argument

This argument holds that Joe Biden would not be a good president because of his inconsistent voting record: across nearly half a century in public office he repeatedly shifted his positions, which the argument reads as a lack of firm principle that makes his future conduct unpredictable. The charge draws on the sheer length and variability of Biden's record. Having entered the Senate in the 1970s and served decades before the vice presidency, he accumulated a voting history that critics argue zig-zags with the prevailing political winds. They point to issues on which his stance changed over time — among them crime and criminal-justice policy, busing and desegregation, financial and bankruptcy legislation, trade, and the funding of abortion — where his earlier votes sit awkwardly with his later positions. To opponents, the pattern is not principled evolution but expediency: a politician adjusting to whatever was popular within his party at each moment, rather than holding a consistent philosophy. The inference to fitness for office is that inconsistency undermines the trust a presidency requires. Voters, the argument holds, need to know what a president actually believes and will do, especially under pressure; a record of shifting positions means his commitments cannot be relied upon, and citizens cannot predict how he would govern on the issues that matter to them. Worse, a leader who follows the political winds may be governed by them in office, swayed by polls or factions rather than steering by conviction. Conviction and consistency, on this view, are core qualifications, and a wavering record signals their absence. From this standpoint, an unreliable record forecasts an unreliable presidency. Because Joe Biden has an inconsistent voting record, this argument holds, he would not be a good president.

Premises

Counter-arguments

Defenders reply that a fifty-year legislative record will contain revised positions by arithmetic rather than by expediency. A legislator voting across five decades, through changing evidence and changing public opinion, will hold views they later abandon; the alternative — never revising a position over half a century — is not usually treated as a presidential virtue. Several of the shifts cited moved alongside substantial changes in the surrounding consensus, notably on criminal justice, where assessments across both parties altered as the effects of the 1990s legislation became clear. The argument also does not distinguish the two things it needs to separate. Expedient reversal and revision in light of evidence look identical in a voting record; telling them apart requires examining the reasons given at the time, which the argument does not attempt. As stated it is close to unfalsifiable, since a consistent record would be criticised as rigidity and a changing one as opportunism, leaving no possible record that would count in the candidate's favour. The inference to unpredictability sits badly with the case at hand as well, since a candidate with a fifty-year public record is among the most extensively documented in modern politics — and defenders argue that responsiveness to a party's centre of gravity is part of what a party's nominee is for. Critics who press this charge more effectively make it specific, naming a position, its reversal, and the absence of any stated reason, rather than resting on the length of the record.

Rejecting the premises

[Rejecting P1] Defenders reply that a fifty-year legislative record will contain revised positions by arithmetic, and several shifts cited moved with substantial changes in the surrounding consensus — including on criminal justice — so variation does not itself indicate expediency. [Rejecting P2] Expedient reversal and evidence-driven revision are indistinguishable in a voting record, and separating them requires examining the reasons given, which the argument does not attempt — leaving a charge that a consistent record would answer as rigidity and a changing one as opportunism. [Rejecting P3] The inference to unpredictability sits badly with a candidate whose positions across five decades are among the most extensively documented in modern politics.
