The Iran deal: Will congressional Democrats choose political power over principle?

As President Obama and Secretary of State John F. Kerry continue to insist this week that the Iran nuclear deal will make the world a safer place, Iranian Supreme Leader Ayatolla Ali Khamenei bragged on Twitter that the pact prevents the "Great Satan" from directly inspecting Iran's nuclear facilities and warned Israel that in 25 years it will no longer exist.
The irony is not lost on the American people, hundreds of whom protested the Iran deal on Capitol Hill yesterday, some carrying signs that read: "What part of 'Death to America,' 'Death to Israel' don't you understand?"
