CLEVELAND -- Ohioans overwhelmingly support transitioning to using 50 percent clean energy by 2030 to deal with climate change, according to a just-released poll..

More than 80 percent of poll respondents back the idea. That includes a majority of Democrats, Republicans and Independents.

The poll was done by Ansalone, Liszt Grove for the group NextGen Climate.

The group is the advocacy organization backed by California billionaire activist Tom Steyer.

He left a job managing billions of dollars in hedge funds for institutions and wealthy individuals. He and his wife have pledged to donate half their fortune to charity..

Steyer was in Cleveland Thursday for a panel discussion on climate change's impact..

"The only reason we're doing this is...we believe it's the right thing to do, " he said.

He is active in political fundraising, and has bankrolled Democratic candidates with big donations.

Some observers call him the flip side of the Koch brothers.

He disagrees with the comparison saying he is not advocating for policies that benefit him financially.

"We have no personal gain," he stressed.

Presidential candidates have been asked to sign a 50/30 pledge.

"We tried hard to get something that would be concrete and would get the candidates to come up with a concrete solution, " he explained.

Thus far, only Hillary Clinton and Bernie Sanders have. Republican candidates have been unresponsive.

"No one has put out a concrete energy plan, " he claims.

The survey concluded most voters do not consider clean energy a partisan issue.

It found 75 percent of Ohio Republicans support the 50 percent by 2030 plan.

"That's a number I've never seen anywhere else, " Steyer exclaimed, surprised at the positive margin.

Less than half of Ohioans believe t Democrats are the only political party that supports clean energy measures.

ALG Research surveyed 1,200 prospective Ohio voters Jan. 14-19. The margin of error is plus or minus 2.8 percent.

Ohio is one of five states where NextGen has established an office.

"This is ground zero for American voting and American public opinion," he said.

Steyer came to WKYC Channel 3 for a one-on-one interview with WKYC Senior Political Correspondent Tom Beres. The interview can be watched in the attached excerpts.
