"What they're obviously worried about is voters showing up as active in multiple states during the same elections". Do mean like Steve Bannon,  Tiffany Trump,  Sean Spicer, Jared Kushner, and Steven Mnuchin ? (https://www.nytimes.com/2017/01/27/us/politics/trump-cabinet-family-voter-registration.html?mcubz=1). They were allregidstered im multiple states.

Wilco73 , who is registered in each state is already public information which this committee (or you or me) can access. This group wants to know who you voted for! That information is none of anyone's business.  The sanctity of the vote is a cornerstone of American Democracy. No one has the right to know who anyone else voted for. That leads to intimidation and voter fraud.

Please think before you goose-step into a line. That line might lead to a gas chamber. Remember Hitler was elected.
