Democratic Lt. Gov. Diane Denish does not have a primary opponent in New Mexico’s 2010 governor’s race and her fundraising shows how determined she is to keep it that way.

Denish laid down a marker Tuesday, announcing $1 million added to her campaign coffers for the second quarter and $2.2 million in the bank.

The campaign noted that “more than two-thirds of those contributions (68%) were for $100 or less,” which it said showed “strong grassroots strength across the state.”

Denish also announced last week that her campaign had already succeeded in collecting nearly three times the 2,163 petition signatures required to qualify for the 2010 ballot.
