First problem: There is no evidence that postal votes have ever distorted a US election; not even in Colorado or Utah, making postal voting possible without major restrictions.
Second problem: Every four years, the US Constitution sets the Tuesday after the first Monday in November as the date set in stone as the election date. No president can change that.
