Feds Harass Grantland
A federal judge ruled that holding both positions put Grantland in violation of the Hatch Act. Thus Grantland decided to retire, instead of leaving the legislature. The Hatch Act prohibits government employees from participating in partisan elections, but is usually only applied to those at the federal level. I haven't seen a specific reason why the judge applied it to Grantland, a state employee, in this situation. Indeed, the U.S. Office of Special Counsel only notified Grantland of a potential violation in the middle of his second term.
Grantland's decision to leave his state job lets the matter drop and it is unlikely the issue will be a major factor in his upcoming race for re-election. But with all the potential conflicts of interest brewing in the state legislature, it's odd that the Feds would choose Grantland, a healthcare worker, to make an example of.
