A very simple way to correct this is to require people to present id before voting.
Re: Lawyers making false charges.
The Democratic National Committee has instructed their lawyers to charge voter intimidation, even where none exists. This directive, if carried out, violates the American Bar Association's Rules of Professional Legal Conduct in almost every single state.
The penalty is a disciplinary proceeding and potential disbarment. Lawyers may be zealous partisans,but no lawyer wants to risk losing his or her law license -- for almost any cause.
The ABA should issue a directive regarding the penalties involved for lawyers using their professional status to make unsubstantiated charges.
