Arizona Dem says state is bluer 'not because Arizona is necessarily a blue state,' but from distaste for GOP 'extremism'

• An Arizona lawmaker says GOP "extremism" has led many state voters to increasingly back Democrats.
• "The Republican party has become extreme in the age of Trumpism," the state senator told Politico.
• Arizona in recent years has become a hotly-contested swing state up and down the ballot.

In recent years, Arizona — after decades as a GOP bastion — has emerged as one of the most prominent electoral prizes for Democrats.
