A 36% approval rating is sky-high for a president that started a pointless immensely costly war after getting elected on a platform of "no more costly wars" and is in the process of negotiating an immensely unfavorable deal with Iran after getting elected on a platform of "Obama's deal with Iran was terrible, I could do much better".

By contrast, Biden at the same point in his term was hovering around 39%, for the heinous crime of... rebuilding the US economy? Including some woke riders in his infrastructure bill?

At this point, a fair assessment of US citizens is that on average, they seem to consider that being a right-wing autocrat wannabe, threatening to invade allied countries "as a negotiating tactic", being a climate change denier, starting a humiliating failed war, trying to blackmail the press into compliance, etc, are about 3% worse than being a cringe center-left bureaucrat.

"US citizens don't seem to care" is an apt hyperbole.

It doesn't help that many of those "center-left" democrats (whatever that refers to) seem to be criticizing trump for letting iran off too easy, not you know starting a stupid war nobody in their right might would want, bombing a school, wasting american lives, driving up prices, risking the global economy, throwing lebanon under the bus... nope, he let iran off too easy.

When the parties are both fucking stupid when it comes to issues that matter, the entire right/left spectrum goes out the window.
