One reason of many it’s a bad idea:
[Illinois Gov. Rod] Blagojevich, Harris and others are also alleged [in the federal indictment] to have withheld state assistance to the Tribune Company in connection with the sale of Wrigley Field. The statement says this was done to induce the firing of Chicago Tribune editorial board members who were critical of Blagojevich.

P.S.: “When the Tribune-owned Chicago Cubs wanted permission to install lights at Wrigley Field, Ald. Ed Vrdolyak let it be known it would require an end to editorial criticism of him. An editorial responded that the Cubs would ‘be playing morning games on a sandlot in Gary first.’ Vrdolyak — this will surprise you — is now headed for prison, another victim of Fitzgerald.” (Steve Chapman, Reason, Dec. 11).
