The latest round of letters questioning the citizenship of some Colorado registered voters has 63 out of 298 people affirming their right to vote, and most recipients are ignoring the May letters altogether.

The letters are part of an ongoing effort by Republican Secretary of State Scott Gessler to address what he says is a risk for voter fraud. Gessler’s office provided the latest numbers to The Associated Press this week. Another 15 people who received letters last month said they weren’t U.S. citizens and asked to be removed from voter rolls.
