The "uniparty" isn't true of everything, but it is true of loving war, all war, and only the "crazies" in Congress will complain about bombing the shit out of Iran, aside from meek process arguments. You are supposed to get our permission first, Mr. President, sir!
The process matters, of course, but most Dem opposition is just theater.
What happens after we bomb the shit out of Iran? Everyone loses interest, as they always do.
