The latest fundraising disclosures show that Democratic Sen. Tom Udall has stockpiled $1.5 million so far for his re-election campaign next year.
Udall raised nearly $875,000 from April through June, and spent almost $264,000.
No Republican challenger has announced plans so far to run against Udall.
Udall's campaign cash balance of $1.5 million is the largest of any member of New Mexico's congressional delegation.
Federal Election Commission campaign finance reports show Republican Rep. Steve Pearce with cash-on-hand of $758,000 in his re-election account at the end of June, Democrat Ben Ray Lujan had about $473,000 and first-term Democrat Michelle Lujan Grisham had a campaign balance of nearly $201,000.
Democratic Sen. Martin Heinrich, who won election last year, reported a balance of $156,000 in his campaign account.
