==Competitiveness== In 2006, [[Republican Party (United States)|Republicans]] had 48 percent of voter registrations, [[Democratic Party (United States)|Democrats]] had 30 percent, and [[Libertarian Party (United States)|Libertarians]] had roughly 5 percent.<ref>[https://archive.today/20070310212125/http://www.sacbee.com/content/opinion/story/14253547p-15069375c.html "Editorial: 4th Congressional District"], ''The Sacramento Bee'', May 10, 2006</ref> A Democratic congressional candidate nearly won the district in 2008, losing by only half a percentage point and less than 1,600 votes, indicating that the district was much more competitive than it appeared to be.

New district boundaries for the 2012 elections shifted the population center to the south and east. Registered Democrats and Independents/Decline to State voters in the new district area outnumber registered Republicans by 12%. However, Republicans, Independents/Decline to State, and small third parties outnumber Democrats well over a 2 to 1 ratio. There were 183,800 Republicans, 117,300 Democrats, and 97,200 others.<ref>{{Cite web | url=https://ballotpedia.org/California%27s_4th_Congressional_District_election,_2018 | title= 2018 California's 4th Congressional District election | website=Ballotpedia | language=en | access-date=March 3, 2019}}</ref> In presidential elections, [[Donald Trump]] won the district in [[2016 United States presidential election|2016]] with 54% of the vote and won in [[2020 United States presidential election|2020]] with 53.7% of the vote.

It includes all of [[Lake County, California|Lake County]] and [[Napa County, California|Napa County]], most of [[Yolo County, California|Yolo County]], and parts of [[Solano County, California|Solano County]] and [[Sonoma County, California|Sonoma County]]. Major cities in the district include [[Davis, California|Davis]], [[Woodland, California|Woodland]], [[Napa, California|Napa]], [[Vacaville, California|Vacaville]], and most of [[Santa Rosa, California|Santa Rosa]].

Roza Calderon was able to successfully collect 322 CDP-credentialed delegate signatures needed to block the endorsement, in which Morse only received 44 delegate votes. However, CDP staff refused to accept the forms after it was alleged they closed doors early to prevent the submission. A petition was later filed with the Compliance Review Commission (CRC)<ref>{{Cite web|title=California Democratic Party Rules Committee Agenda and Packet|url=https://www.cadem.org/our-party/standing-committees/body/FINAL-Rules-Packet-071118.pdf|website=California Democratic Party}}{{Dead link|date=November 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> by Calderon. The CRC voted to accept and count the signatures, ultimately disqualifying enough signatures to proceed with Morse's endorsement.
