Well done. I think it was assumed that, because of the demographics of the District, a way left candidate would do well. You did a good job of showing how the District is actually "just left of center". We've seen that black voters appreciate Biden's approach and are not particularly enamored of Sanders. The Jewish vote in Cleveland probably isn't strongly pro-Bibi but nor is it pro-Palestine. There are more than just a handful of conservative and Orthodox Jews in Cleveland and Akron.
As a "left of Sanders" voter, I would have been happy with a Turner win but am neither surprised nor upset that Brown got the nod. It's not like she's going to send up trial balloons about privating Social Security.
