Phil Scott, who's been lieutenant governor for five years and was a state senator for 10 before that, says he will announce Tuesday what has long been expected: He's running for governor in 2016.

Scott, 57, a Republican who lives in Berlin and co-owns an excavating company, plans to hold a campaign kickoff later this fall. He will face a primary race against retired Wall Street executive Bruce Lisman of Shelburne, who announced his candidacy last week. 

So far, two Democrats have also announced their plans to run: House Speaker Shap Smith of Morristown and former state senator Matt Dunne of Hartland. Transportation Secretary Sue Minter of Waterbury could follow with an announcement of her own shortly.

Democrat Peter Shumlin, the three-term incumbent, announced in June he is not running for reelection.
