Exactly, and that's how we can easily predict he would've started another long-term war in his second term. Well, that...and the fact that he asked about his authority to start bombing Iran's nuclear facilities, AFTER he had already lost the election. Dude is just another neocon like GWB, but he needed his first term to grift as much money from taxpayers as possible.
You have no evidence of that, it's a maybe at best.
By...being black? I don't remember him once mentioning race, outside of perhaps black history month or events like Trayvon Martin.
Oh, there are so many examples of Obama and his administration leveraging race to achieve political objectives. I seem to remember his Justice Department dropping cases of voter intimidation when the New Black Panther Party was involved. Obama has always maintained that the country was divided along racial lines, and the policies of his administration reflect that.
Obama's warm relations with Cuba led to large-scale repression of Cuban dissidents, resulting in over 9000 (ha!) arrests in Castro's regime. Legitimising the regime must've been very popular with Cuban Americans, I'm sure - that explains why they started siding with Trump all of a sudden when Biden entered the race this year. Obama even upgraded their interest sections to full-blown embassies - how nice. If Trump is "best buddies" with Putin, Obama was BFF's with Castro.
At the same time, he refused, or made it as difficult as humanly possible, to enforce immigration policy when it comes to the border with Mexico, culminating in DACA. The result is a giant mess at the border - Joe knows who built the cages, and so does Obama.
You're also correct about cases of alleged persecution of black suspects by the police. Obama was always first in line to shed a tear on television whenever a tragic incident had occurred, even before all facts were known. He created an illusion of the police ganging up against black people when statistics don't support the existence of any substantial bias in encounters with officers.
He was partisan, not a moderate - it was his way or the highway. If his ideas couldn't get support, he famously said that he had a phone and a pen, and was happy to use both. Trump isn't innocent in this regard, but it was Obama who normalised the practice of the executive overstepping its bounds.
The notions of "systemic racism" or "unconscious bias" gained prominence under his watch, not Trump's, and there's little evidence to support either. According to surveys around 60% of Americans agree that race relations have suffered, not improved under Obama, and I tend to agree, but that's a large subject better-suited for another thread. With that said, a Biden presidency looming over the horizon forecasts a return to the same failed policies of pandering and race-baiting.
You sure do have a selective memory. How exactly was birtherism not divisive? How exactly is racism not the problem here, and at what turn did Trump fail to tap into that racism?
Birtherism was always about the eligibility to run for office and never about Obama being black. According to Biden, he was a "good black" anyway - I quote, "I mean, you got the first mainstream African-American who is articulate and bright and clean and a nice-looking guy. I mean, that's a storybook, man" - truly a wordsmith-elect. The DNC absolutely used race as a cudgel during Obama's presidency, any criticism of the President was always met with the lazy excuse of "well, you're saying that because you're a racist". As far as I'm concerned, Obama could've been a purple unicorn, that wouldn't change my opinion of his presidency, which was poor.
