AUGUSTA, Maine (AP) Former Maine Gov. Paul LePage has registered as a candidate for governor in the state once again.

LePage was a Republican governor from 2011 to 2019. He has long hinted that he might challenge Democratic Gov. Janet Mills in 2022.

LePage and Mills were frequent rivals when LePage was governor and Mills was the state’s attorney general.

The Maine Ethics Commission website stated on Thursday that LePage is an active candidate based in the Lincoln County town of Edgecomb.

Under Maine law, a former governor can serve again as long as they never serve more than two consecutive terms.
