The uniqueness of Lincoln's beard

[Eva Elisabeth]

Some male candidates for the Presidency in 2016 better start growing some facial hair then as a protection against Hillary...

If a woman can be easily taken down in a political debate we use to say (here in the Netherlands) “ze heeft haar op haar tanden”, literally translated in English: "she has hair on her teeth”. Is that the female equivalent of a moustache?

Kees, I think you mean if she can NOT easily be taken down, i.e. she's a tough customer?! (There's the same idiom in German, "Haare auf den Zähnen haben".)
