The race to replace Diane Feinstein features three Democratic members of Congress and a former Major League Baseball star. Steve Garvey, a former Major League Baseball star, has joined the Senate race to fill the vacant seat left by Diane Feinstein. California's open primary system allows all the candidates to compete in the same primary election. Garvey, as the only Republican candidate, could have a significant impact on the race and potentially make it to the runoff. The leading Democratic candidates include Adam Schiff, Katie Porter, and Barbara Lee, who each bring their own strengths and appeal to different voter demographics. The debate will be a crucial moment for the candidates to introduce themselves to the voters and showcase their policy knowledge and charisma. Garvey's focus on solving California's homelessness crisis may resonate with conservative primary voters. The leading Democratic candidates are expected to address the issue of homelessness and balance empathy with the need for action.
