A Travis County election judge claims he's discovered 1,800 active registered voters who were inadvertently deleted from county voter rolls since 2004.

This, after the county admitted last week to sending out 8,500 letters to names deleted in an earlier purge, when the county's database was joined with a new statewide system.

Mike Conwell volunteers as an election judge; he makes his living as a database administrator.

"I get very frustrated when bureaucracy gets in the way, or somehow infringes on that right to vote," Conwell said.

The first batch of deletions reported in the press was blamed on difficulties in reconciling the county system with the state's.

Conwell says the 1,800 deletions he discovered have more to do with clerical errors, like carelessness in data entry or mishandling forms.

But Travis County Tax Assessor-Collector Nelda Wells Spears disputes Conwell's numbers.

"I don't think there is any number like that in terms of data entry problems. I don't think Mr. Conwell knows what he's talking about there," said Spears.

Conwell keeps a list of the 1,800 people he found with deleted records, and even provided current phone numbers of many of the voters.

"I'm a little irritated because I now have to go down to the voter registration office and re-register to vote, when I never asked to be deleted from the system," said Allison Attal, who discovered she was deleted sometime after voting in 2006.

The Secretary of State's office recommends all voters check online to make sure their registration is current.

It's not too late to register or re-register to vote in the March 4th primary. The deadline is February 4th.
