The U.S. House races are intensifying as Election Day approaches, with Democrats showing signs of improvement following Vice President Kamala Harris's nomination. Key battlegrounds include Oregon's 5th District, where a recent poll shows incumbent Republican Lori Chavez-DeRemer and Democratic challenger Janelle Bynum in a tight race. In California's 13th District, a rematch between Republican John Duarte and Democrat Adam Gray is critical, as Duarte's previous victory was the narrowest in recent history. Additionally, Maryland’s 6th District is also competitive, with Republican Neil Parrott leading Democrat April Delaney by a slim margin. Analysts note that Latino voters will significantly influence the outcomes in California's crucial races, where major PACs are investing heavily in advertisements. As Democrats aim to flip five seats to regain control, the dynamics in these districts will be closely watched.
