Background: Francis "Frank" Hague, born in Jersey City, was the fourth of eight children to John D. and Margaret Hague (nee Fagen), immigrants from County Cavan, Ireland. He was raised in Jersey City's Second ward, an area known as The Horseshoe due to its shape which wrapped around a railroad loop. The ward was created when the Republican-controlled legislature gerrymandered a district within Jersey City in 1871 to concentrate and isolate Democratic, and mostly Catholic, votes. By age 14, Hague was expelled from school prior to completing the sixth grade for poor attendance and unacceptable behavior.
Context: Hague's use of voter fraud is the stuff of legend. In 1937, for instance, Jersey City had 160,050 registered voters, but only 147,000 people who were at least 21 years old--the legal voting age.  In 1932, Governor Moore appointed a lawyer named Thomas J. Brogan, who had served as Hague's personal attorney in corruption hearings, to an associate Justice seat on the state's Supreme Court. Less than a year later Brogan was named as Chief Justice. In at least two instances of alleged voting fraud in the 1930s (Ferguson v. Brogan, 112 N.J.L. 471; Clee v. Moore, 119 N.J.L. 215; In re Clee, 119 N.J.L. 310), Brogan's court issued extraordinary rulings in favor of the Democratic machine, in one case asserting that the district superintendent of elections had no authority to open ballot boxes, and in another case ruling that the boxes could be opened, but no one had the right to look inside. Brogan also assigned himself to the Hudson County jurisdiction, thereby controlling the local grand jury process and squelching other election fraud cases.  Although Hague, like other political bosses of the time, was not above outright fraud at the polls, the keys to Hague's success were his matchless organizational skills and demand for complete loyalty from his subordinates. His command over the Democratic voters of Hudson County, a densely populated urban area in a state that was still mostly rural, made him a man to reckon with among state Democrats and Republicans alike. He was a close friend of Al Smith, the New York governor who would become the first Irish-American presidential candidate in 1928. In addition, Hague's support of Roosevelt for President was rewarded with a steady stream of perks that sustained Hague's organization throughout the Depression.
