She did not lie, she joined the blue dog democrats in 2014, in 2013 was advocating for border security and making immigrants learn english.  In 2018 she ran on being an Independent Democrat and voting against the party.
One third of Arizona voters are Independents, Ruben Gallego has Arizonas 3rd congressional district, which is basically just the city of Phoenix.  His politics dont align with the rest of the state which are primarily conservative, Voters are not going to elect him.  He would be a bad candidate to put up against Sinema.
Good. Sinema lied to the people of Arizona, she doesn't deserve a second term. Gallego seems like a great candidate with a strong legislative track record
