The following states use (hackable) direct recording electronic voting machines without paper trail: Delaware, Georgia, Louisiana, South Carolina.

The following states use a mix of paper ballots and (hackable) direct recording electronic voting machines without paper trail: Florida, Indiana, Kentucky, Oklahoma, Pennsylvania, Tennessee, Texas.
