Both sides, in good faith

The strongest fair case each way — we don't pick a winner.

The case for

Supporters of Trump's high-profile involvement argue that a president's endorsement is a legitimate and time-honoured tool of party politics, helping voters identify candidates who will govern in step with a shared agenda. They see his rally appearances and rhetorical flourishes, such as urging supporters to "pretend I'm on the ballot", as effective mobilisation that boosts turnout in what might otherwise be a low-attention runoff. For these voters, leaning on a popular figure's brand to unify the base and secure a working majority is simply smart, standard campaigning rather than anything untoward.

The case against

Critics, including some within Republican ranks, worry that campaigns built so heavily around one individual's persona can crowd out scrutiny of a candidate's own record, priorities and fitness for office, particularly when that candidate hails from an established political family and might otherwise need to earn support on personal merit. They argue that turning a local primary into an implicit referendum on a single leader risks reducing voters' focus on substantive local issues and concentrates political power in ways that sit uneasily with a healthy, pluralistic party system. For them, treating a protester's interruption as a punchline further illustrates a rally style more focused on spectacle and loyalty than on open debate.
