>Not sure what do you mean here. I don't think there is a law that prevents a person to run for presidency after the election's failure, but I don't know anyone who tried several elections either.

I don't say there is a law. It is a tradition. Anyone cannot elect third time for president anyway.

A president again will president application next time. It's a tradition.

An applicant can't be applicant if fail the election. Tradition.

Anyone cannot elect thirt time. Rule.

Our media so close american elections. So we know a lot of unnecessary things about USA... :)
