From 1887 to 1890 he served as the 34th
Lieutenant Governor of Massachusetts under
Governor Oliver Ames. For significant portions of 1888 and 1889 Brackett served as acting governor due to Ames's illness, notably representing the state in that capacity at the celebration of the centennial of
Ohio's settlement, and at the dedication of the
Pilgrim Monument at
Plymouth. During his year in office, Brackett continued his advocacy of cooperative banks, securing legislation exempting their stock from state taxes. a predecessor to today's
MBTA, Boston's public transit system.
Henry Whitney, the West End's president, was criticized for the tactics he used to gain legislative approval for the charter, which included
bribery of legislators, the retention of a large number of paid
lobbyists (including former Governor
William Gaston), and payment for favorable press in local newspapers. The West End also did not immediately begin active use the charter, in part because of questions of high liability in the city's crowded business district, and over the suitability of extant elevated rail technology in Boston's geography. This failure to act brought further charges that the charter had been acquired to
squelch competition. Brackett's term in office marked a low point in the state Republican party, and he was described by historian Richard Harmond as "pliable and mediocre". The party was internally divided between the Mugwumps and Blaine supporters, as well as between its younger and older leaders. The state's liquor control laws were a major subject that also caused the party some difficulty. Much of the party leadership was generally in favor of such laws, but opposed outright prohibition. For political purposes, the party had in 1886 formally declared support for a state constitutional amendment banning alcohol, but this had failed to draw significant support from the temperance community. A popular referendum for the enshrinement of prohibition in the
Massachusetts State Constitution failed in 1889, upsetting advocates of prohibition, and Brackett took up their cause in a different way. Although he had opposed the amendment, he ordered stepped-up enforcement of the existing laws, which closed bars that did not serve food. There was a popular backlash, and Republican appeals to anti-Catholic nativist sentiment also drove many French-Canadian Catholic supporters into the Democratic fold. These combined with the negative effects of the
McKinley Tariff on the Massachusetts economy to cost Brackett reelection. He was defeated in the 1890 election by Democrat
William E. Russell in one of the most successful elections for Democrats in the state since the
American Civil War. ==Later years==
