Veteran Republican Sen. Susan Collins has a commanding fundraising advantage in her much-watched bid for reelection.
Campaign filings made public on Friday say Collins has raised $10.9 million, the most by any political candidate in Maine history.
Her closest challenger, Democratic Maine House Speaker Sara Gideon, has raised $7.6 million. Collins has sailed to reelection in the past, but this year she’s facing a tough test for a fifth term.
Democrats have used her vote in favor of appointing conservative Supreme Court Justice Brett Kavanaugh in October 2018 to make the case she’s out of touch with many Mainers.
