Former Vice President Al Gore has joined Hillary Clinton on the campaign trail – along with nearly every other notable Democrat still living – to stump for the nominee during the final few days of the election.

But Gore didn’t just speak on behalf of Clinton when he appeared alongside the nominee in Florida this week. The environmental advocate also spoke out against the most controversial amendment on Florida’s ballot this year: Amendment 1.

This amendment, though it is dressed up to sound pro-solar, is actually working in the interest of energy companies across the state and helping to suppress consumers’ rights to own and sell their own energy harvested from the sun.

Said Gore:

“They are trying to cloud the truth by putting forward a phony, baloney initiative that sounds like it protects solar. It doesn’t protect solar. The things they claim protect solar are protections you already have. But they are trying to fool you into amending your state constitution in a way that gives them the authority to shut down net metering and do in Florida what they’ve done in Nevada and just kill the solar industry.”

Gore isn’t the only one speaking out against the amendment, and there has been a strong grassroots effort in Florida to educate voters about the proposed amendment.

Those who aren’t sure if voting against the seemingly pro-solar amendment is the right idea need only to only look at who is behind the funding for the amendment – Gulf Power, Duke Energy, Exxon Mobil, and several other energy companies. If that isn’t enough to convince you, the Koch brothers have also given generously to the amendment.

If the amendment fails, it will ensure that Floridians retain the rights in relation to solar, rather than giving it up.
