In 1812 Strong was convinced by Massachusetts Federalist leaders to come out of retirement to run once again for governor. War with Britain was imminent, and the Federalists sought a strong candidate to oppose Elbridge Gerry, who had been victorious against Christopher Gore in the previous two elections. Gerry, who had originally been somewhat moderate, became increasingly partisan during his tenure, and Federalists viewed Strong's earlier success in office and relatively modest demeanor as assets. Strong's victory in the election, which saw the Federalists also regain control of the legislature, was attributed to several factors: Federalists capitalized on the partisanship of the recent redistricting of the state that resulted in the coining of the term "gerrymander", and there was strong antiwar sentiment in the state. Strong was reelected by wide margins in the following war years.
