I hope the use of the word admittance was a deliberate gaffe designed to taunt her detractors.

Palin is not using bad diction here. We are not French where there is only one word for each definition. English is a textured language; Palin's use of ADMITTANCE instead of ADMISSION is both accurate and and has a more active-present feel. (MITTERE is the Latin active form of the verb to send. MISSI-,MISSUM are perfect and passive, respectively.)

Those who have a problem with using "admittance" should go back and read some more Fowler.

To a “Gaffe Hunter” if she holds her facial expression wrong its a ‘gaffe.’

Reread your definition. The “act of admitting” refers to allowing someone to enter. As I was granted admittance to Studio 54 by the guy at the velvet rope.
