Republican Senate candidate and Texas Attorney General Ken Paxton addresses his Democratic opponent’s current lead in the race and his plan to get his message to voters.

Jacob Smith, who worked for Cornyn for five years as a deputy legislative director and policy advisor, signed up to work on the Senate campaign for Talarico. The news was first reported by NOTUS and
