I was noticing Steve Raby has a moustache and goatee while Mo Brooks is clean-shaven. FReeper Auh2orepublican has a theory that clean-shaven candidates have an advantage over the facially hirsute. Personally, I have no bias in that direction, since I also have a moustache and goatee... ;-)
My theory is about candidates with stand-alone mustaches, not with goattees. But, yes, I assume that Raby starts off with a disadvantage (although keep in mind that Alan Grayson of FL sported a goattee when he was elected in 2008).
it’s an aversion to masculinity.
