Imposing such an issue may well be what single-issue politics concern; but for the most part success is rather limited, and electorates choose governments for reasons with a broader base.
In the 1880s, the third government of William Ewart Gladstone made British politics in practical terms single-issue, around the Home Rule Bill, leading to a split of the Liberal Party.
Single-issue politics are a form of litmus test; common examples are abortion, taxation, animal rights, environment, and guns.
The National Rifle Association in the United States, which has only one specific interest, is an example of a single-issue group.
The term single-issue voter has been used to describe people who may make voting decisions based on the candidates' stance on a single issue (e.g., support or opposition to abortion rights, or in support of gun rights or gun control).
The existence of single-issue voters can give a distorted impression: a candidate's overall views may not enjoy the same support.
