Democratic Rep. Ruben Gallego begins TV ads as the Arizona US Senate race takes shape without Sinema
Democratic Rep. Ruben Gallego began airing the first television ads of his U.S. Senate campaign on Tuesday as the crucial Arizona race takes shape as a one-on-one contest after incumbent Kyrsten Sinema declined to run for a second term. Gallego's ad introduces him to voters as a U.S. Marine who served in a unit that faced especially fierce fighting in Iraq and lost 48 men. The Arizona race is one of a handful of contests that will determine control of the Senate.
