“I think it's tight,” the Anchorage Republican said before the vote. A veto override in Alaska requires a three-fourths majority of the entire legislature.

Palin rejected the Department of Energy money in May and continues to defend the controversial move.

"As Governor, I did my utmost to warn our legislators that accepting stimulus funds will further tie Alaska to the federal government and chip away at Alaska's right to chart its own course," Palin wrote on her Facebook page Sunday. "Enforcing the federal building code requirements, which Governor Parnell and future governors will be forced to adopt in order to accept these energy funds, will eventually cost the state more than it receives."

"There are clear ropes attached, and Alaskans will soon find themselves tied down by codes which will dictate how we build and renovate homes and businesses. The state has hundreds of millions of dollars already budgeted for conservation, weatherization and renewable energy development. Legislators don't need to play politics as usual and accept these funds and the ropes that come with them."

State lawmakers dispute Palin's objections to the stimulus money. In a letter to Alaska House Finance Committee Co-Chair Rep. Mike Hawker and obtained by CNN, the Department of Energy wrote that the Alaska legislature "does not need to adopt, impose and enforce a statewide building code" in order to qualify for the energy funds.

Palin originally threatened to reject more than $400 million of the state's $930 million share of the stimulus package. Eventually Palin signed off on all but the three percent under consideration Monday by state lawmakers.
