Kyrsten Sinema pulled off the Democratic Party's biggest win of the election by running as a centrist.
Her victory in the Arizona Senate race is a contrast to some other high-profile liberals who tried to turn red states like Georgia and Texas blue. Sinema became the victor over Republican Martha McSally on Monday after a slow count of mail-in ballots.
Sinema is an openly bisexual former Green Party activist who remade herself into a centrist.
She ran promising to be a nonpartisan problem-solver and hitting McSally over her vote to weaken protection for people with pre-existing medical conditions. She did not attack President Donald Trump and treaded lightly on immigration.
That's a volatile issue in Arizona with its growing, Democratic-leaning immigrant population.
