The Biden campaign is reportedly looking at buying more television and digital ads in key battleground states as polls indicate the race is tightening. According to Politico, Democratic sources familiar with the discussions said the Biden campaign is “increasingly concerned” about the tightening of polls in key states like Wisconsin and Florida. The Biden campaign is reportedly considering additional television, digital and radio ads in those states to expand its reach and secure support. The campaign has already made major advertising investments in states like Wisconsin, Michigan and Pennsylvania, as well as nationally. The Biden campaign is also reportedly exploring advertising in states like Arizona and North Carolina, which have become more competitive than expected. The move could signal an effort by the Biden campaign to shore up its lead in some battleground states and shore up its support among key voter groups, such as women and young voters.
