But it’s not a celebration of President Donald Trump’s nomination.
Republican Voters Against Trump, which highlights the voices of everyday members of the party who are disaffected with the president, says the spot will air on Fox News during the convention in the swing states of Pennsylvania, Wisconsin, North Carolina, Arizona and Florida.
Trump won all of those states in 2016, which combine for 85 electoral votes, but Biden has an edge this year in all five, according to polls.
The new ad will also run on digital media outlets in the battleground states.
Republican Voters Against Trump is one of several anti-Trump groups hitting the president from the right.
However, it’s unclear whether these efforts will move voters.
