Sen. Michael Thibodeau, R-Waldo, announced Monday on his Facebook page that he is dropping out of the 2018 race for governor.

Thibodeau represents Maine Senate District 11, which comprises all of Waldo County.

On Monday afternoon, he posted a message to the Mike Thibodeau for Governor Facebook page stating his priorities as Senate president, leader of the Senate Republican caucus and a business owner.

"Over the last few months, I’ve come to realize there just isn’t time to do all of these things and run for governor at the same time," he said.

Thibodeau has served four terms in the Senate and emerged as a moderating voice in the GOP by opposing fellow Republican Gov. Paul LePage's 2015 tax overhaul and other measures. He has reached the term limit and cannot run for re-election.

"I am truly disappointed to have to make this decision, but I believe in my heart it is the right thing to do," he wrote, going on to thank his family and supporters.

"I got into this race because I wanted to make Maine a better place for our citizens to live and work, and I have decided to withdraw from this race for the same exact reason. There is much work to be done, and I look forward to continuing the fight for strong communities and a growing economy."
