It seems the leftwing Gannett droids at the Indianapolis Star never give up on their march towards the left (and irrelevancy).
The campaign manager wrote a letter to the editor with a response to the Star's endorsement of (and free advertisement for) his Democrat opponent. Who doesn't seem to have money for rent much less a congressional campaign.
The Star initially agreed to published the letter until "Superior editors" - in other words likely Denny himself - spiked it.
Hoosier Access has the letter in its entirety.
