Democrat Aaron Carroll of Limerick is running against Republican Heidi Sampson of Alfred in the race for the House District 21 seat.

The district covers Alfred, Newfield and parts of Limerick, Parsonsfield and Shapleigh. The winner on Nov. 8 will succeed independent Rep. James Campbell Sr. of Newfield.

Carroll, 39, is a farmer and forester and the chairman of the Limerick Planning Board.

In his responses to a Portland Press Herald survey, Carroll said he opposes background checks for private gun purchases and opposes marijuana legalization.

He said he neither supports nor opposes the ballot proposal to raise Maine’s minimum wage to $12 an hour by 2020, but has concerns about the effects on small businesses, consumer prices and tip earners.

Sampson is a business owner who says on her Facebook page that she wants to reduce regulations on small businesses, control insurance and medical costs for seniors, and reduce taxes and reform welfare.

Sampson did not respond to survey questions about her background and positions on key issues.
