I have roundly criticized Obama for the last 17 years since he was elected. I was critical during his tenure, and critical of his actions after his tenure. He doesn't get a pass.
I voted for him in 2008, not because he was black, or because he was a Democrat, but because I was sick of no-bid contract loving Neo Cons whose stock portfolio was antithetical to national security, and thus I wanted and voted for change.
But let's look at his actions and what I disliked.
Drone strikes? Yup. Critical of those. Bailing out Wall Street? Yup. Some of those bankers should have been jailed, versus bailed out with golden parachutes. Continuing the forever wars in the Middle East? Of course I critiqued those. Ignoring actions by our "friends" in the middle east that furthered Arab hatred of the US? Absolutely hated that too. Trying to pacify Putin after his attacks in Georgia, invasion of the Donbas? Yes. Was particularly hard on him for this. Not standing up to the GOP reactionary wing? Yes, I blamed that on him too. Failed healthcare policy? Of course I have issues with that.
Let's stop pretending that Obama was some sort of liberal or far leftist. The dude was pretty center-right by world standards, and only considered remotely left because the GOP had spent the Bush II administration pushing the Overton window about a hundred quadrillion light years to the right.
I could go on. But as someone who spent some time in GOP heavy rural areas during one of Obama's campaigns, I can tell you a lot of the people in those areas routinely began their critiques of Obama with a word that starts with an N and ends with an -ER.
