After the war, Dale decided to remain in Portsmouth and open his legal practice there. He soon found his way into politics; he was first elected city solicitor in 1921 and later mayor from 1926 to 1928. He went back to legal practice but was elected in 1933 to the state senate, where he served as president. In 1937 he was elected to the Executive Council of New Hampshire. He returned to the state senate, then again served at the Mayor of Portsmouth from 1943 to 1944. He entered the Governor's race and during the Republican primary election defeated incumbent Governor Robert Blood. Dale then went on to win the general election and win reelection for a second two-year term.[1]
Dale retired from politics in 1948 to work in banking and radio in New Hampshire.[1] He died in 1978 in Portsmouth.
