The 30-second ad, released just hours ahead of Tuesday night's Democratic primary debate in Iowa, features a montage of Trump saying Biden's name, followed by a narrator saying, "Donald Trump has made it clear he's got Joe Biden on his mind because Trump knows Biden will beat him in Pennsylvania, Michigan and Wisconsin — the states we need to take back the presidency."

The ad, first obtained by CNN, focuses on winning in the general election instead of emphasizing the Democratic primary. Biden has led the field of White House hopefuls in most national polls, but not in early nominating states like Iowa and New Hampshire.

"Whoever we pick has to have [a] really good chance of being able to beat Donald Trump, and you guys have to decide who is best equipped and most likely to beat him," Biden told voters in Anamosa, Iowa, earlier this month.

Tuesday's ad is part of an ongoing $4 million ad buy in the Hawkeye State, which holds its first-in-the-nation caucuses on Feb. 3.
