The most votes a recount changed in a statewide election in the last twenty years was the Minnesota Senate race of 2008. And even then it was around 440 votes.
Only two other recounts in recent history changed the results of an election.
-The Washington Gubernatorial election of 2004 (<400 votes changed)
-The Vermont state auditor election of 2006 (<400 votes changed)
Even if another Minnesota happens, Oz wins by 400.
He is right to start campaigning for November now.
There are 10,000 votes yet to count.
