But Biden’s polling numbers in the Democratic primary have declined in recent months, and his fundraising has also lagged — he collected $7 million less between July and the end of September than in the second quarter.
Biden’s looming cash crunch

Joe Biden’s middling $15.2 million third-quarter fundraising haul is raising fresh questions about whether the former vice president’s campaign can withstand a new onslaught of Republican ad attacks while simultaneously waging a battle for the Democratic nomination.
Biden’s campaign has long framed his candidacy around the idea that he can beat Trump in a head-to-head contest, particularly in the battleground states that were central to Trump’s 2016 victory over Hillary Clinton.
His latest fundraising round was more than $9 million behind his closest rival in the polls — Elizabeth Warren. His total also ran well behind Pete Buttigieg and Bernie Sanders.
