The Contra Costa Times reports on a California law allowing one candidate to enjoy increased contribution limits.

Contra Costa County supervisor candidate Erik Nunn of Oakley and his relatives have contributed or loaned his campaign more than $25,000 and triggered an increase in his opponents’ contribution limits.

Incumbent Supervisor Federal Glover of Pittsburg and challengers Gary Agopian, Mary Rocha and Don Parscal are now permitted under the county’s election law to receive as much as $5,000 per person rather than $1,675 for the June 3 election.

Nunn called it a mistake and said he has refunded the money that pushed him over the limit.

“My family did not know the rules, or how much I had already lent the campaign,” said Nunn, a chief financial officer for a general contracting company. “It definitely was something that my treasurer and I missed. … I have already sent the contributions back to my family members and the correction will be made on my next campaign report.”

But it’s too late for Nunn to reverse course.
