Tom Steyer is telling potential supporters that if he were to run for Senate in California, he would set policy goals related to climate change, taxes and public education.
If he does not meet certain goals in six years, Steyer would pledge not to run for a second term, his potential supporters told The Sacramento Bee.
Steyer, a Democrat, would push for the United States to lower its greenhouse gas emissions to 1990 levels by 2020, the Bee reported. The goal reflects one California set in 2006.
Steyer also wants to ensure that the highest income earners pay effective tax rates that are at least the same level as the middle class.
It is a version of the Buffett Rule, a proposal named after investor Warren Buffett. Steyer said he wants to put an end to carried interest, reform capital gains taxes and close tax loopholes, the Bee said.
His goal for education would be to expand the public education system to include college, beyond the current kindergarten to high school.
Steyer said last week he would decide soon whether to run for the seat that will be open in two years when Sen. Barbara Boxer (D-Calif.) retires.
