Changing color on single link in navigation

Hey Everyone,

I am attempting to change the color of one link in the navigation. I set up a political site at gtumminello.com and I would like to make the contribute link red in the navigation bar. I set up a class for it, but I can effect everything else but the color. I thought this would work.

a.contribute:link { color: #FF0000; text-decoration: none; }

a.contribute:visited { color: #FF0000; text-decoration: none; }

a.contribute:active { color: #FF0000; text-decoration: none; }

a.contribute:hover { color: #800000; text-decoration: none; }

Not sure why it’s not working. Was hoping that one of you could enlighten me.

Thank you in advance
