GOP incumbents raise funds for expensive fight to keep seats

"It’s a similar situation for Rep. Mimi Walters, R-Irvine, who won re-election in a 58 percent landslide in 2018 and has raised nearly $1.1 million this year.

Despite having a district with a 40 percent to 30 percent GOP registration edge, Walters, who was first elected in 2014, is facing four Democratic challengers, including three who already have raised at least $200,000."
