A Smart Politics analysis of 83 general election cycles dating back to 1850 finds that the Democratic Party now comprises a larger percentage of Californians and New Yorkers in the U.S. House than at any point since California joined the Union.

When the 113th Congress convenes in January, 29.4 percent of the 201-member Democratic caucus will hail from California (38 members) and New York (21 members).

That marks an increase from the two-state delegation’s collective previous all-time high of 28.1 percent recorded after the Republican tsunami of 2010 (increasing for a few months to 28.5 percent after Kathy Hochul’s win in NY-26 in 2011)…

While California and New York are two of the three most populous states in the country, it is important to note that the number of representatives from the two states collectively has remained relatively flat over the last 50 years.
