Democrat Tammy Baldwin has raised more money than her Republican opponent Tommy Thompson in recent weeks and had more cash on hand for the final push toward Election Day.
Baldwin reported Monday that she started October with $3.5 million, while Thompson said he had nearly $2 million.
Baldwin said she raised nearly $4.6 million over the three-month period that ended Sept. 30. Thompson said he raised $2.2 million since the Aug. 14 primary. He did not say how much he raised over the three-month reporting period.
Neither candidate's report was immediately available on the Federal Election Commission website. Both campaigns reported some numbers from the report, but did not provide the actual paperwork they had to submit.
Polls show a tight race with three weeks to go.
