Mississippi Democrat Mike Espy raised $1.4 million during the first 18 months of his long-shot bid to unseat incumbent Republican Sen. Cindy Hyde-Smith. In the three days since Supreme Court Justice Ruth Bader Ginsburg died, Espy raised $1 million.

Fundraising for Democratic Senate candidates has exploded since Ginsburg, a beloved liberal icon, died on Friday. That evening through Tuesday afternoon, online donation platform ActBlue processed $170 million in contributions overall to Democratic candidates and groups. Some of that cash is flowing to Democratic challengers running in red states whose path to victory is virtually nonexistent regardless of how much money they rake in. Espy is one.
