You can always write in John Galt. 

 There is third party 

 NOTA > third party 

 You can't vote blank in the US? https://en.m.wikipedia.org/wiki/Protest_vote 

 If they allowed that there'd be a high risk of blank being elected 

 You can vote write-in and vote literally “none of the above” (or anyone, my grandfather has recently taken to voting for his friend down the street). 

 There's only been one candidate worthy of write in for decades.
