Bernie Sanders's "America" TV ad was the highest-rated campaign ad for making viewers feel happy and hopeful, according to a study. Spotcheck found that 80 percent of viewers said it made them feel at least a little happy and hopeful — including more than half of the Republicans who watched it. When asked how often they'd run the "America" ad, more than half of those surveyed said they would advise the campaign to run it a lot, including 51 percent of Republicans and almost 60 percent of independents.
