Only 10 percent of voters who were affected by the Maryland computer glitch casted a provisional ballot in last month's primaries, according to election officials.

This is below the election's average of about 25 percent.

Thousands of Maryland voters who changed their voting information in the past year found out that had to cast provisional ballots in order to participate in the primary.

Originally, the error was estimated to have affected over 80,000 voters, but elected officials found that the number was just under 72,000.

In a panel held in Annapolis, Md. on Thursday, elected officials were under fire about the computer glitch.

"I am personally deeply sorry for what occurred," said Christine Nizer, Administrator of the Maryland DMV.

Nizer also said that she was concerned that this voting error may have had a deterrent effect on voters since people may believe that their one vote doesn't matter.

Every provisional ballot is counted in Maryland, regardless of whether it would affect the outcome. Ballots are counted the second Wednesday after the election.
