CHARLOTTE, North Carolina — President Trump, a former reality TV star, likes to tout his ability to pull an audience. But his appearances during the 2020 Republican National Convention’s first night didn’t help his party outperform Democrats, at least by that metric.

Roughly 15.8 million people turned on their TVs between 10 p.m. and 11 p.m. Monday to watch the Republican convention’s opening night, according to early Nielsen Media Research data.
