With the deal over Iran's nuclear program announced, the White House will turn its attention to selling it to Congress -- and it will be depending on one lawmaker to save President Barack Obama's foreign-policy legacy: House Minority Leader Nancy Pelosi.
While the former House speaker has yet to publicly support any Iran deal, her behind-the-scenes campaign to whip votes to protect it has already begun. She has urged her Democratic colleagues to back the president. She has hosted informal meetings with experts who support the negotiations to educate her caucus. She even helped gather lawmakers' signatures for a May 7 letter to Obama expressing support for diplomacy with Iran, though reserving judgment on a final deal.
