Nevada state Assemblywoman Heidi Kasama announced her bid Monday to represent the state's 3rd Congressional District. The race is expected to be one of the most closely watched in the country. Kasama is looking to unseat Democratic incumbent Susie Lee, who narrowly won last year. The swing district, which includes parts of Las Vegas and Clark County, is considered the state’s most competitive. Kasama, a Republican, says she'll focus her campaign broadly on education, economic development and public safety. She didn't outline any specific policy proposals in her announcement.
