G.Elliot Morris has crunched the numbers:
I wrote on Saturday night, a few hours after Trump announced the U.S. bombing of Iran, that people should generally expect an increase in support for military action over the next week. I made that prediction for two reasons.
First, because there was a positive shock in support for past wars in the Middle East just after the U.S. government engaged in its initial attacks. The surge was anywhere from 10 to 20%, depending on the war. With history as our guide, that’s a pretty strong trend.
This prediction turned out to be right; According to YouGov, support for bombing Iran rose from 21% to 35% over the last week, and opposition dropped from 57% to 46%.

It’s the Republicans of course:
[I]n surveys conducted after the strike on June 21, Republican support for Trump’s actions has surged. In YouGov’s polling, 68% of Republicans now support Trump bombing Iran. Meanwhile, support among Democrats didn’t budge at all, and Independents moved just 9 points toward support.
Still, as Morris points out, “the bombing is still the least popular act of war in the Middle East since at least 2001.” So that’s something.
The Washington Post poll found this:

They beieve in Dear Leader, not isolationism. America First=whatever Daddy wants.
