In 1808, Morril was elected as a member of the
New Hampshire House of Representatives; he served until 1816. The legislature elected him as the

In the 1824 election, Morril received the most votes; however, because he failed to win a majority of the votes cast, the election had to be decided by the legislature. Morril was elected by a vote of 163 to 43 during a joint meeting of the New Hampshire legislature. In the 1825 election, Morril ran unopposed; in the 1826 election, Morril defeated his opponent
Benjamin Pierce by 5,392 votes. In the 1827 election, Morril was defeated by Pierce by an overwhelming margin: Benjamin Pierce won 21,166 votes out of 27,411 cast. ==Personal life==
