*Counting Joe Lieberman as an essential Democrat
**The size of the house massively increased in these years, so those numbers may be a bit misleading

This does not count independents that are elected and caucus with one party (with the exception of Lieberman). Let me know on what you think are wave years. There are some years (like 1978 for Republicans and 1982 for Democrats) that I would say are good years for either parties, but don't qualify as a wave. Its also important to consider the outside circumstances, the reasons why years like 2014 and 1936 are wave years is because the respective party was already close to the ceiling in the House. I think the House better represents the country than the Senate so I based more of my choosing on that.
