When Republicans sent a letter to Iranian leaders this week, “inappropriate” was likely not the word they had in mind.
Forty-two percent of Americans say it was inappropriate for the 47 Senate Republicans to send a letter to Iran’s leaders, warning them Congress has to approve of a nuclear deal, according to a new Huff Post/YouGov poll.

Twenty-eight percent say the letter was appropriate, while 31 percent remain unsure.
A clear division down party lines exists about the letter: Democrats are more likely to say the letter was inappropriate (71 percent) than Republicans (53 percent). Thirty-seven percent of Independents thought the letter was inappropriate, compared to 26 percent who thought it was appropriate.
Americans are also divided on who they trust more to handle the Iran situation: 36 percent pick President Obama, compared to 31 percent who pick congressional Republicans. A third (33 percent) are unsure.
The poll of 1,000 U.S. adults was conducted March 10-11, with a margin of error of plus or minus four percentage points.
