Retired Navy Captain Hung Cao has won the Republican nomination for the U.S. Senate in Virginia, positioning him to challenge Democratic incumbent Sen. Tim Kaine in the upcoming November election. Cao, endorsed by former President Donald Trump, secured a decisive victory in the primary, garnering approximately 65-75% of the vote against four other candidates. His campaign focuses on border security, economic growth, and opposition to Biden administration policies. Cao, a Vietnamese refugee, emphasized his military service and criticized Kaine's long tenure in politics. Incumbent Senator Kaine, who has served in various political roles including governor and vice-presidential candidate, has already raised substantial funds for his re-election campaign, making the upcoming race highly competitive.
