The Washington Post notes:
But though Wells remains popular on Capitol Hill and in pockets of Northwest and Northeast Washington, he remains untested before a citywide electorate. Wells will have to convey what his self-described “progressive” views mean for the black middle-class voters who often decide elections in the District.
In normal English, white people really like Wells. However, in order to win in DC, you need some black votes and it’s not clear that blacks will vote for Wells because he’s white.
Wells has been remarkably effective as a Council member, even though he’s the only white dude on the Council. He basically follows the strategy that Sailer comments on here, of thinking of "regulations as tools." For example, are your sidewalks in crappy shape? If so, you don’t complain about the disrepair, nor do you mention that you want a livable, walkable city. Instead, you complain that handicapped people can’t get around on the sidewalks. Bam, the law requires new sidewalks.
