WASHINGTON – Gwen Graham's Democratic opponents have attacked her 2015 vote in Congress for the Keystone pipeline, but one of the biggest spenders in party politics, billionaire environmentalist Tom Steyer, doesn't seem terribly concerned.

"There's going to be a lot of things to take into account," Steyer told the Tampa Bay Times when asked if Graham's vote would give him any pause of Democrats nominating her.

"We continue to be huge believers in the idea that we should not spend one more dollar on fossil fuel infrastructure," he said. "The transition to a clean, renewable economy has got to happen and it's got to happen as soon as possible."

He called the Keystone pipeline a "dramatically stupid idea."

Steyer's comments came during a discussion about his 2018 election plans that includes a significant Florida presence and playing in the race for governor, Sen. Bill Nelson's re-election bid and flipping three GOP-held congressional seats.

More on that tomorrow morning.
