Background, money and policy
No candidate in the listed field has a biography on file. That means the record does not establish details such as their work history, education, public service or connection to Maine beyond their entry in this race.
No totals are on file for money raised, money spent or cash on hand for any candidate. Those categories describe campaign receipts, campaign expenses and the amount remaining in a campaign account.
There are also no documented policy positions on file for any candidate. The record therefore does not establish where Costello or any of the other candidates stands on matters that may come before the U.S. Senate.
What happens next
The candidate field and official campaign records may change before Election Day. Candidate qualification, ballot access and future financial filings are parts of the election process to watch as the Nov. 3, 2026, general election approaches.
Voters can also look for formal policy statements from each campaign. Until positions are documented, no issue stance can be assigned to Costello or another candidate in the race.
