Recount won’t solve the problem. Fraudulently cast votes have identical looking ballots with NO NAMES OF VOTERS.
Only thing which will solve the problem is a national voter ID issued upon presentation of citizenship evidence. Then no voting by mail, and every voter must present the national voter ID.
Could you advertise in the precincts that went 100% for Obama asking if anyone voted for Romney to come forward?
Voter ID only takes care of controlling the input to the voting system.
It does not control the means of COUNTING the votes.
Votes can to e deducted from one candidate and added to the other.
