People registering for the rally submitted a phone number when they requested tickets, and that information was used to match the person with party voting data. (It’s unclear how many of those who registered online attended in the venue or in the overflow outside.)
An estimated 70% of registrants were Hispanic, according to the data.
Two-thirds had voted in two or fewer of the past four elections, per the data.
The El Paso County Coliseum, where the event was held, holds about 6,500 people, the El Paso Times reported. The El Paso Fire Department told the paper the attendance "might be 10,000 with the people outside."
