Other Dems may follow Schumer against deal | Ames Tribune
The majority of undecided senators, like Chris Coons, D-Del., Claire McCaskill, D-Mo., and Joe Donnelly, D-Ind., are rank-and-file members who seem determined to either keep their own counsel or stick to their own review process before making a personal decision on the matter. But some leading figures — such as Sen. #Ben Cardin, D-Md., the ranking member on Senate Foreign Relations — are also on the fence. Cardin could arguably sway an even greater flock than Schumer once he makes a decision.
Cardin, for his part, has not said when he will declare himself. But he has been pushing for the administration to provide the text of side agreements between the International Atomic Energy Agency and Iran to Congress. But those agreements do not appear to be in the offing.
