Michigan's Ballots are Pubilc Documents---why not Aspen's?

The Michigan Attorney General today handed down an opinion confirming that voted ballots in Michigan are public documents.

If Michigan citizens can look at their ballots? Minnesotans' theirs, Floridians theirs, why not Aspen?

If Longmont, Colorado citizens can be involved in post elections using real ballots why are Aspen's ballots secret?

If El Paso County (Colorado Springs) can have extensive citizen post election audits, why do Aspen's ballots have to be hidden away from all but the city officials?

See a full explanation from  the Michigan AG's opinion, demonstrating that ballots are to be non-traceable to the voter. The same facts and logic should apply here.
