On January 15, 2007, Delaware Senator Robert L. Venables announced that he was planning to introduce the National Popular Vote bill into Delaware Legislature for the 2007 session.

In 1966, Delaware Attorney General David P. Buckson (R) filed a lawsuit on behalf of the state of Delaware and 11 other predominantly low-population states (including North Dakota, South Dakota, Wyoming, Utah, Arkansas, Kansas, Oklahoma, Iowa, Kentucky, Florida, Pennsylvania) against New York concerning New York’s use of the winner-take-all rule in presidential elections. Under the winner-take-all rule (also called the "unit rule" or "general ticket" system), all of a state's electoral votes are awarded to the candidate who receives the most popular votes in each separate state. In State of Delaware v. State of New York, the plaintiff states argued that New York's use of the winner-take-all rule effectively disenfranchised voters in their states. The Supreme Court declined to hear the case (presumably because of the well-established constitutional provision that the manner of awarding electoral votes is exclusively a state decision). Ironically, the defendant (New York) is no longer an influential closely divided battleground state (as it was in the 1960s). Today, New York suffers the very same disenfranchisement as most states because it too has become politically non-competitive. Today, a vote in New York is equal to a vote in Delaware: votes in both are equally irrelevant in presidential elections.
