Bill Lynch makes his move

Good timing is perhaps the most valuable of all political commodities, so with a Democrat coming into the White House, it makes perfect sense that Bill Lynch, chairman of the RI Dems, has made a pitch to be our next US attorney.
Brother Patrick, who is running for governor, has enjoyed relatively good poll ratings in the last year or so -- particularly for someone working in the political minefield-laden office of AG. And Bill has paid his dues with the Democratic Party.
Yet is there a point where two brothers occupying/seeking high-level government posts hurts the fortunes of one of them?
