Wilkerson backers take the low road

Dianne Wilkerson is counting on a big turnout of black voters for Barack Obama to boost the desperate write-in campaign she’s waging after losing last month’s Democratic primary for state Senate to Sonia Chang-Diaz.  Despite Wilkerson’s effort to hitch her wagon to the Democratic presidential nominee, I suggest in my column in yesterday’s Boston Globe City Weekly section that the veteran Roxbury lawmaker’s write-in drive has taken on some of the worst qualities of the John McCain campaign.
