The best way to look at it is to ask “if he cared less about his appearance, and dressed more slovenly - would it excuse his abhorrent views and stances?”.
If the answer is no, then it should be a non-factor.
A cynical part of me thinks that some of the more outlandish politicians dress that way (Trump’s hair dye and fake tan, JD Vance’s guyliner, Boris Johnson’s unkempt hair, etc.) are done in part as an attempt to de-rail reporting by having us fall into the easy trap of ridiculing their appearance rather than criticising their views and actions.
I don’t think Russia’s affording all that much nowadays… last I heard, they were experiencing liquidity issues trading with China?
