I hesitated when it came to accurately describing one of my Senators, Chuck Schumar. I will respectfully disagree that he has "always acted and communicated responsibly about our Mideast ally." But I can respect that you think he has, or currently is.
I would also strongly disagree that the genocide in Gaza was in any way those pesky republicans way to deliberately divert and divide the Democratic Party. I could be wrong, of course, but I'm pretty sure that on October 7, 2023, when the terrible attack on Israel took place, that Joe Biden was president. More, as I remember it, President Biden was assumed to be our party's candidate for re-election, right up to July 21, 2024, when he was replaced by VP Harris.
The Biden-Harris policy on Gaza was indeed unpopular with some Democrats, including numbers of them in specific states. Yet that was insignificant in terms of determining the election's outcome, when compared to its impact on independent voters.
I will also add, fully recognizing this may be my lonely opinion alone, but I think that all Democrats need to grasp that our country's well-being is tied directly to our position among the other nations of the world. And that the war in Iran has severely damaged that around the globe.
