Vox's Ezra Klein has settled on Al Gore, who, he wrote, will tackle the "existential threat" of climate change, while GOP Senator Jim Inhofe, R-Oklahoma, "is throwing snowballs on the floor of the Capitol because he believes cold weather outside his office proves global warming a hoax."
Klein also points to Gore's ability to self-fund a campaign, a key consideration in taking on Clinton, who is expected to have a deep reservoir of funds for her presidential run. Since he left the political world, Gore has become a rich man, making millions from his shares in Apple, his sale of Current TV to Al Jazeera, and several other ventures.
There are some challenges, however. "The problem with a Gore candidacy, to be blunt, is Gore," Klein wrote. "His relationship with the press is challenging, to say the least. He is an aging politician in a country that loves new faces."
