Many misunderstandings here.

Arguments take their merits from themselves, not from the writer's nationality (or authority by whatever source).

A political "whore" actively exercises erotic charms on powerful persons in order to be promoted. While most powerful persons are heterosexual men, attractive women have best opportunities - but increasingly, men are found in the same role, particularly in homosexual contexts. I do not know a derogatory slang word for these, but I am sure one exists. Maybe "slut" is used for either sex.

Inevitably, attractive successful women and men can become suspects (and thus subject to false rumour and malicious accusation), if a respectively susceptible hierarchy can be alleged.

It seems however that money, family ties, military merits, ethnic and religious affiliations etc. play more important roles in the corruption of power than sex and erotic attraction. The latter makes better drama; the topic of "Evita" can be seen in Shakespeare's tradition.
