I'm reatrded can I still Vote???

I'm excited to support John McCain, the Republican candidate for President.  Having just turned 18 it seems like an opportune time to ask if I can legally vote.  You see, I am legally retarded.  Are there laws preventing us retards from voting?  I'm sure Sen. McCain you use my vote and the votes of my closest friends, who are also retarded.

Please advise.  TIA

Because Democrats are the ones who have been running our country into the ditch the past eight years.
