Dan Osborn, a nonpartisan candidate for the U.S. Senate, has submitted over 12,000 signatures to qualify for the November ballot in Nebraska, far exceeding the 4,000 required. He aims to challenge incumbent Senator Deb Fischer, who is seeking her third term, while no Democrats are running for the seat. Osborn's campaign emphasizes its grassroots nature, with significant public engagement and a focus on addressing 'broken politics in D.C.' despite skepticism from Fischer's campaign about his support. Recent polling shows him within striking distance of Fischer, with a poll indicating a two-point deficit. Fischer's campaign has raised significantly more funds, totaling nearly $6.3 million compared to Osborn's $1.6 million. The Secretary of State's office will verify the signatures, with a decision expected by September 13.
