Obama's election was sold as a positive milestone for race relations. Once he was president he devoted almost no time at all to race relations, and conditions for many PoC actually deteriorated, because he discarded his popular base instead of creating an integrated social movement.

(Ironically - if that's the word - Trump has been far better at creating the latter than Obama was.)

A lot of people actually believed the Hope and Change slogans. But it turned out there was no real cause for hope, and very little significant change.

And that's marketing for you - illusion over substance.
