Colorado Secretary of State Donetta Davidson says the state Attorney General's office isn't investigating cases of voter fraud quickly enough.
But she says she feels the election can be managed properly.
Davidson says she sent hundreds of suspicious voter registrations to the Attorney General's office in April, but just one person has been charged with fraud so far.
Chief Deputy Attorney General Don Quick says his office has received about 150 questionable registration forms but adds investigations take time. The original documents have to be found and submitted to handwriting analysts.
Davidson also says she'll ask for a grand jury investigation if she finds reason to believe the election won't be fair and accurate.
Davidson also will convene a task force on voter fraud after the election with citizens and legal experts. She says the panel will advise her in making legislative recommendations.
