Obama was a hollow zero used by his masters to push their agenda, not his; the two most obvious examples are 1) his public opposition to “gay marriage” morphing into making it the law of the land, and 2) his desire to improve the lot of blacks in the US, then basically pandering to the foreigners imported to replace them. Few blacks today have anything kind to say about Obama anymore; it was no accident that Black Lies Matter started in the waning days of his presidency. They knew they’d been had, and eight more years of immigrants had moved past them on the socio-economic ladder.
Something that's been consistent throughout his career has been his support for illegal immigrants over Americans. There's even a passage where he implies that we couldn't function as a country without foreign labor.
I totally disagree that blacks of today do not hold Obama in high regard. As someone who has worked with many blues collar blacks and shared social as well as work related events, I have yet to hear a single criticism off the great Obama. When confronted with questions of his accomplishments, they refused any dialogue even when confronted with his policies they privately with which vehemently disagree.
