Bull semen

Something else I learned today: Colorado could be collecting millions upon millions of dollars more in annual revenue if not for various exemptions that industries have carved out over the decades.  The state currently does not charge a tax on sales of bull semen.  Changing that would put $1.5 million into the state's coffers each year, and wouldn't require voters' approval.

I'm not questioning the importance of bull semen to the state's economy, but I imagine that, if given a choice today, voters would rather see that $1.5 million going to the public schools.
