Romney was dogged by negative perceptions about his Mormon faith during his unsuccessful 2012 bid for the presidency. But new research shows attitudes about Mormons are warming, just as they are for most other faith groups in the United States.
Using a “thermometer” to gauge opinions about various religions, the Pew Research Center said American feelings about Mormons improved from 48 to 54 degrees since 2014.
“The increase in mean ratings is broad based,” Pew said in the February report titled “Americans Express Increasingly Warm Feelings Toward Religious Groups.”
“Warmer feelings are expressed by people in all the major religious groups analyzed, as well as by both Democrats and Republicans, men and women, and younger and older adults.”
