While Mitt Romney has made himself the face of the Republican establishment opposition to Donald Trump, the 2012 GOP presidential nominee ran a campaign that foreshadowed the path that Trump would take to front-runner status in this year’s GOP primary.

Romney has been making robocalls to voters in Arizona and Utah urging them to vote against the brash businessman-turned-presidential candidate. The former Massachusetts governor last week decried “Trumpism” as associated with “racism, misogyny, bigotry, xenophobia, vulgarity and, most recently, threats and violence.” He is backing Texas Sen. Ted Cruz in a bid to deny Trump an outright majority of delegates before the convention.
