I don't think that's how it works, well it is but I think with any public figure you run the risk of making it about their identity rather than the issue at hand, I think if you reference things Dominic Cummings has done then that may be off putting to some but the more that people call him out by name the more it also falls on death ears, in these polarised times I see a lot of people that will blindly stick up for Dominic Cummings because he is their man and when there's been worse breaches of lockdown and every day people see people they know having made minor breaches etc then hearing the name Dominic Cummings just comes across as grating and hypocritical. I could be wrong but I think bringing up Cummings usually just cements peoples opinions, I think it's a reductive way to make a wider point.
