What does "dogged by" mean in this context?
Context: "Sturtz’s description of Mrs. Obama’s reaction – that she was “pretty aggressive,” that she “got into my face” – was breathtaking bit of projection and entitlement that also tiptoed dangerously close to the “angry black woman” stereotype that Mrs. Obama has been dogged by for years."
If you are dogged by something, you are followed or pursued or accompanied relentlessly, persistently, by something, and usually the something is undesired.
"the stereotype that Mrs. Obama has been dogged by for years." = "the stereotype that has been dogging Mrs. Obama for years." =
"the stereotype that has been following and clinging stubbornly to Mrs. Obama's trail for years."
If you do something doggedly, you do it pertinaciously, stubbornly, like a dog with a single-minded focus on tracking something, as in "He followed me in dogged pursuit."
When you "dog" someone, it means you're criticizing them. In this context It's a way of saying that she has suffered the stereotype of being an "angry black woman."
It's a strange way to use "dogged" in my opinion, but I suppose it's not uncommon.
