DES MOINES — As opening days go, it could have been better. Or safer, at the least.The first day of the Iowa Legislature’s 2021 session one week ago featured the normal opening-day remarks from both Republican and Democratic leaders. But most noteworthy about Day 1 was the public rally with hundreds of people packed into the Iowa Capitol rotunda to protest mask-wearing and other emergency public health orders.There was nothing illegal about the rally and it was peaceful.But that made it no less irresponsible and dangerous.
