By wide margins, Republican incumbent Gov. Susana Martinez continued to raise and spend more campaign money than all of her would-be Democratic opponents, according to the finance reports filed Monday with the Secretary of State’s Office.

In the second round of reports for this primary season, Martinez said she had raised more than $561,500 since early April. The governor spent nearly that much — about $552,500 — mostly for television ads. That leaves her campaign with more than $4.2 million in the bank.

Martinez raised more than twice the amount reported by all of the Democrats put together. Even before Monday’s reports, the incumbent’s huge fundraising edge was one reason the Democratic Governors Association decided against pumping money into the New Mexico governor’s race this year.
