Ever since 1956, a reference book called “America Votes” has been published every two years, after each congressional election. It has been by far the best election returns publication for the United States. Sadly, the publisher has discontinued it and there will be no “America Votes 2024”.
Each volume had the county-by-county vote for every general election within each state for president, U.S. Senate, and Governor. Each volume had maps of the U.S. House boundaries. Each volume had vote returns for every ballot-listed candidate, and for the declared write-ins as well. Each volume also had primary election returns, including presidential primaries. Each volume also had a summary of past U.S. Senate and gubernatorial elections from 1946 to the present day. The books were typically about 525 pages for presidential years, and 475 pages for midterm years.
Most large and medium-sized public libraries in the United States carry the books.
Before the internet existed, states published books containing their own election results, but almost all states have stopped doing that, because the results are generally on state election office websites. But they are often difficult to find and can be difficult to read. Also some states tabulate the write-in votes for declared write-in candidates, but do not put those write-in totals on the state websites.
