CNN's John Berman was left momentarily speechless by new polling data on President Donald Trump's war in Iran.New polling data presented by the network's Harry Enten suggests Democrats have failed to capitalize on public unease over the 80-year-old president's handling of the Iran conflict, and Berman expressed surprise by the findings."The president's approval rating is sagging, the war in Iran is widely unpopular, so you'd think that Democrats, you might think that Democrats in Congress could see some kind of boost in the polls on this subject," Berman said. "You might think that, but you'd be wrong ... Man, I'm tongue-tied because actually these numbers surprise me. I was looking at them, and I am surprised that they are like this."Two separate polls released this month found Republicans holding a narrow edge over Democrats on the question of who is more trusted to handle Iran policy, Enten said. A CNBC poll found Republicans ahead by two points, and a CBS News poll released just a day later showed the identical two-point advantage."Now, one poll is one thing, but you put the two of them together, and you can see that the American people, simply put, are not buying what Democrats are selling on Iran," Enten said. "They still trust Republicans more. Even if you look at President Trump's approval ratings on the subject, and they're negative, too, but yet Republicans and Trump still more trusted than Democrats are."More striking, Enten said, is the direction of movement over time. A Washington Post-Ipsos poll from April had shown Democrats slightly ahead on Iran trust, by two points. Since then, the numbers have flipped in Republicans' favor — suggesting that as the war has dragged on, public trust has shifted toward the GOP rather than eroded, defying expectations that prolonged conflict would benefit the opposition party."The Democratic Party in the minds of the American public are weak, weak, weak," Enten said.Net approval ratings for Democrats in Congress hovered around negative 40 points in late February, among the lowest levels ever recorded for the party. That unpopularity, Enten suggested, may be undercutting Democrats' ability to convert dissatisfaction with Trump into political trust for themselves, even among some Democratic-leaning voters who remain unhappy with their own party's direction heading into the fall elections. - YouTube youtu.be
