First, thanks to TABOR, the Metropolitan Football Stadium District would have to get a ballot initiative passed to "stick it to the taxpayers" in the 6 county district (unless of course they could figure out how to "charge fees" to folks in the district because "fees" aren't covered by TABOR). 

Second, before the naming rights were initially sold, the MFSD polled voters about selling the naming rights - and something like 80% said they'd be happy to pay the extra penny on $10 indefinitely (that's what the tax was at the time) to keep the name Mile High Stadium. They ignored the polls and sold the naming rights. 

I wonder what the results of a similar poll would show today - and whether a ballot initiative to reinstate that tax would pass IF the initiative included verbiage about the name being Mile High as long as the 1/10 of 1% tax was in effect.
