The measure would make it illegal for election officials to send out unsolicited mail ballot applications, empower partisan poll watchers and ban practices such as drop boxes and drive-through voting that were popularized in heavily Democratic Harris County last year, according to a final draft distributed by legislative staff to voting right advocates Saturday morning.

In a last-minute addition, language was inserted in the bill making it easier to overturn an election, no longer requiring evidence that fraud actually altered an outcome of a race — but rather only that enough ballots were illegally cast that could have made a difference.
