Another Shade of White

Mayor de Blasio is expected to announce he’s running for president next week, according to four sources with knowledge of the plans.
The 2020 announcement could come as early as de Blasio’s birthday on Wednesday, when he’ll turn 58, two sources said. The kickoff was initially expected this week but pushed back, according to another source.
De Blasio’s federal political action committee, Fairness PAC, recently polled Iowa voters. The PAC also bankrolled the mayor’s recent travel to key early voting primary states, including trips to Nevada, Iowa, New Hampshire and South Carolina.
I’m curious as to the drugs used to interpret that Iowa poll as favorable to DeBlasio. I’m less curious as to why DeBlasio thinks he would be a good president because, after all, he’s a white man and they all think they’d make the best president.
