Submitted Biography: "Raised in Southern Indiana, Curtis was a good kid, an Eagle Scout even. However, he embarked on an unconventional path, dropping out of college after his freshman year at Purdue University. After a couple of years in the pizza business, he built a real estate firm with his younger sister Rhonda. In his late 30's, Curtis earned his bachelor's degree from the University of Louisville, working at times as a substitute teacher, and for UPS. After that, he did a year of social work school, and rotated between activism, blogging, and Kentucky politics, even running unsuccessfully for state senate in 2012. In 2014, Curtis was exposed as the source of a unflattering recording of Senator Mitch McConnell, leading to a politically-inspired FBI investigation triggered by McConnell. Curtis decided to make the best of the situation and moved to California to attend Whittier Law School. While studying abroad, Curtis met his husband and love of his life, Rodolfo. They'll be celebrating their 10th anniversary this summer.After graduating from law school, at 47 years old, Curtis moved to Oregon to work for a non-profit focused on climate change. In 2018, Curtis returned to Southern California to practice immigration law, eventually starting two law firms. His newest firm, Red Eagle Law, L.C., is based in Bonsall. It specializes in federal litigation on behalf of immigrant families, and employees attorneys and paralegals across the country. "

Curtis Morrison (D)
Curtis believes Congress should serve as a check and balance on the Executive branch, and that’s not happening with our current representation. While the incumbent, Rep. Darrell Issa, wrote a book called “Watchdog,” lately he has co-sponsored legislation to put President Trump’s picture on the $100 bill, nominated him for the Nobel Peace Prize, and sponsored a bill to help the Trump administration evade review by federal judges. Curtis doesn't think that is watchdog behavior, but rather, lapdog behavior.
People in this district depend upon the Affordable Care Act (as implemented through Covered California), Medicare, and Medicaid more than ever, but these programs are not perfect. Congress should be working on ways to improve outcomes from these programs, not on ways to dismantle and abolish them to fund tax cuts for the rich.
Curtis Morrison (D)
DUE PROCESS OF LAW: Trump’s use of the Alien Enemies Act to hurriedly disappear people to CECOT without due process of law is unlawful. Anyone on US soil deserves due process. Anything less is not who we are.
IMMIGRATION: Immigrants should be treated fairly, and with dignity and respect. This doesn’t mean everyone gets to come to the US. Rather, it means our immigration policies should be orderly, rational, and transparent.
FIRE PREVENTION: We must give firefighters our full support, and that means funding mitigation.Curtis Morrison (D)

I believe in government accountability, but think that's only possible with checks and balances where the congressional and judicial branches hold the executive branch accountable.
This is an especially important issue in this election, as the incumbent Darrell Issa has no interest in holding the executive branch accountable.

General election race ratings
- See also: Race rating definitions and methods
Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:
- Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
- Likely ratings indicate that one party has a clear edge, but an upset is possible.
- Lean ratings indicate that one party has a small edge, but the race is competitive.[1]
- Toss-up ratings indicate that neither party has an advantage.
Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.[2][3][4]
