Anyone can say they're a "write in candidate." But even if he were Mitt Romney he wouldn't have standing for quo warranto (as distinguished from a ballot challenge, where any candidate on the general election ballot or any candidate on a Democratic primary ballot would have standing). To have standing to bring a quo warranto suit, you have to be the person who would hold the office if the incumbent were disqualified. That would have been John McCain before January 20, 2009; today, it's Joe Biden. No one else has quo warranto standing (except the U.S. Attorney or the Attorney General).
im not gonna bet cause you could be right, but im hopeing he has standing on this issue.
I'll give you 10 to 1 odds; my $10,000 against your $1,000.00. We'll place our money in escrow with any Freeper we mutually agree on.
