WASHINGTON, Wall Street Journal, Jan. 20, 2016

Adam Bozzi, a spokesman for Democratic Sen. Michael Bennet said “Iran is further from obtaining a nuclear weapon today than it was five months ago because of the [Iran deal],”. “As implementation moves forward, it is critical that we increase our oversight of Iran’s compliance with the agreement and of its nuclear program.”
After months of diplomatic negotiations and a summer of wooing skeptical lawmakers, the administration began lifting sanctions on Iran this weekend as the accord officially went into effect. But for the agreement’s Democratic supporters, the political debate over the deal is far from over.
Many House and Senate Democrats agonized this summer over whether to support a deal opposed by many Jewish voters, who worried the release of as much as $100 billion in Iranian oil money frozen in overseas accounts could be used to fund terrorism. They did so reluctantly and have pressed the administration to hold Iran’s feet to the fire.
For example, many Democrats spent the first half of January urging the White House to impose separate sanctions on Iran for its two ballistic missile tests this fall. The administration delayed the sanctions on Dec. 30 after Iranian officials said they would view any new sanctions as a violation of the July accord. U.S. officials issued the sanctions on Sunday, saying they had held off to avoid derailing a prisoner swap with Iran completed over the weekend.
 “The Iran deal was to stop Iran from having nuclear weapons capability. That has been accomplished,” Senate Minority Leader Harry Reid (D., Nev.) said on the Senate floor Tuesday. Still, like many Democrats, Mr. Reid has urged the administration to maintain strict oversight of the regime. “Iran must continue to be monitored with intense scrutiny,” he warned.
The Iran nuclear deal would become a much bigger political liability on the campaign trail if Iran does produce a nuclear weapon or take other antagonistic actions, Democratic strategists said.
The Iran debate is resonating more in a year when national security issues have flared up repeatedly
on the campaign trail.
