This is probably a joke thread, as per the original poster's name being 'dictator' - inspired by the Borat movie, perhaps? - but I will answer it seriously anyway, as something does come to mind.
My neighbour is the ex-secretary of my country's Communist Party, and met Mao in the '70s. I don't recall him ever smelling of anything. He is in his 90s now, however, and devotes all his time to his writing.
I would suggest something of Caron's.
First, Caron was founded by he immortal Ernest Daltroff, who, like Marx, was a Jewish intellectual of sorts. Who that smelled anything of Daltroff's could not consider him an intellectual? He is the only perfumer whom I admire as a human being. What thoughts he had, and commemorated in his perfumes. Were Marx a perfumer rather than a philosopher, I suspect he might have done something a little like Daltroff did. Like many Jews, Daltroff fled Paris during WWII, and sought refuse in America. He died not long after returning to France after the war.
Second, Caron is alone among all the French perfume houses in having had the liberty of women at the forefront of their minds from the very start - well, from at least as early as 1919. Tabac Blond was devised as a tribute to flappers, to either complement or conceal their smoking cigarettes, which until then were the exclusive indulgence of men. Then there was En Avion, released in 1929, to commemorate the very first female pilots. I believe that Caron was alone in endorsing the somewhat subversive boundary-pushing of women, and their attempts to leave the oppression of former eras behind them. Daltroff seems to have genuinely admired them. Inherently a somewhat communist thing, this admiration for revolution. 'You have nothing to lose but your chains.'
Third, Caron spends a pittance on advertising than other houses do. Compared to Caron, Guerlain is like Coca Cola. So a left-winger could go with Caron with a clearish conscience in respect of not feeding a commercial hype machine. They are very well-priced, too - highly affordable. Which chances to coincide with their being the only French house that still produce true extraits, keeping the tradition alive so to speak.
On the whole, I think that a communist probably ought not wear a scent at all; did not Lenin abandon music, which he loved, from the thought that it was born of a pre-revolutionary system, and would distract him from his particular ideals? Nevertheless, were s/he to wear something, I think En Avion would be a good choice, suggesting as it does ascent, freedom, and so on, as well as its historical background.
Anyway, just my thoughts. You should probably just go with lavender or patchouli oil, if you want to be perfectly orthodox!
