As a total of 42 Senate Democrats have now pledged their support for the Obama administration's nuclear deal with Iran, public support for the deal continues to decline, A new Pew poll found that only 21% now support the bill and a greater than a 2 to 1 ratio of supporter oppose it.
Pew's new results found a 12-point decline in support since asking Americans about the issue six weeks ago. The survey found that while just 21% approve of the agreement, 49% disapprove (a 5-point rise since mid-July) and 30% have no opinion (an 8-point increase).
Pew notes that while "the partisan divide over the nuclear agreement remains substantial," support for the bill has declined across the board, even among Democrats:
Currently, 42% of Democrats approve of the agreement, while 29% disapprove and an identical percentage has no opinion. In July, 50% of Democrats approved, 27% disapproved and 22% had no opinion.
Republican support for the agreement, already low, has dropped even further (from 13% to 6%). Independents’ support for the agreement also has fallen (from 31% to 20%), although – as with Democrats – the share disapproving has held steady since July, at 47%.
Pew also found that fewer people now say that they have heard "a lot or a little" about the agreement, declining from 79% in July to 69%, with those saying they've heard "nothing at all" increased from 21% to 30%. The findings led Pew to conclude that the "contentious debate over the Iran agreement has not resonate widely with the public."
The results of the poll arrive as the final Senate Democrats announced their positions on the deal. The final tally: 42 have pledged their support, giving the Democrats enough votes to block a Republican resolution of disapproval. Tuesday, Sens. Richard Blumenthal (D-Conn.), Sen. Gary Peters (D-Mich.), and Sen. Ron Wyden (D-Oregon) all announced "in rapid fire succession" they would back Obama, with Sen. Maria Cantwell (D-Wash.) adding her name later that evening as the 42nd Democrat to back the bill. All Republican Senators have announced their disapproval.
The Pew survey of 1,004 adults was conducted Sept. 3-7.
