Former New York Mayor Michael Bloomberg is blanketing television airwaves in Ohio and Texas with $15 million in television advertising, an eleventh-hour bid to push Democratic nominee Joe Biden past President Trump in two states rich with Electoral College votes.

The late investment was announced after Bloomberg’s political advisers polled battleground states looking for places where an additional barrage of television ads might be effective at moving votes to Biden during the final week of the presidential campaign. After reviewing the data, the billionaire media mogul concluded his efforts might be most effective in Ohio and Texas, in addition to the $100 million he is already spending on Biden in Florida.
