When people hear the name Mitt Romney the most common real descriptive word that springs to people’s mind is “rich,” just behind “no/no way.” If you treat “rich” and “wealthy” as basically the same response, then it is by far the most common concept people use to describe Romney. This is a big swing from earlier in the primary season when Romney was primarily associated with his Mormon faith and almost no one primarily associated him with his huge wealth. From Pew:

Romney’s repeated gaffes related to his personal fortune are having a real impact on his popular image. He is no longer viewed as “that Mormon guy running for President,” he is now starting to be viewed as “that extremely rich guy running for President.”

This association of Romney with his wealth will likely get even more prominent during the campaign as Democrats try to depict him as someone out of touch with the concerns of regular Americans.
