While Trump has seen increased fundraising since securing the nomination, he still lags significantly behind Biden’s totals.
Biden has received the majority of his campaign donations from big donors, with 35% coming from contributions over $2,000.
In contrast, 61% of Trump’s funds have come from small donors, reflecting a 10 point increase for Biden from big donors compared to Trump.
