The strong organizational support between the Democrat party has been on display in recent weeks. President Obama has worked closely with party leaders such as Senators Harry Reid and Nancy Pelosi to explain the deal to its 46 Senate Democrats and 188 House Democrats. Experts like Department of Energy secretary and nuclear physicist Ernest Moniz became a prolific voicefor the agreement's ability to curtail Iran's nuclear capabilities, which drew in Senators like Maria Cantwell, the last Democrat to step out in favor of the deal. The efforts of Democrats has overshadowed the Republican's media campaign against the deal, whom have provided no alternatives to President Obama's negotiations with Iran.
