As the corruption trial of former Massachusetts House Speaker Sale DiMasi proceeds apace, it’s instructive to track the coverage in Boston’s two dailies.

From Monday’s Boston Globe:

The witnesses expected this week include David Simas, a White House adviser and Patrick’s former deputy chief of staff; Doug Rubin, a Democratic strategist who helped manage both of Patrick’s campaigns and served as the governor’s chief of staff; Leslie A. Kirwan, Patrick’s former budget chief, who is now a top financial officer at Harvard; and David Morales, the governor’s former commissioner of health care finance.

From Monday’s Boston Herald:

Members of Gov. Deval Patrick’s first-term administration will be sucked into the drama of former House Speaker Sal DiMasi’s corruption trial this week. Former Administration and Finance head Leslie Kirwan left during Patrick’s first term but had a key role in the computer software contract that DiMasi allegedly helped steer toward Cognos. David Simas, Patrick’s former deputy chief of staff, also could be called to the stand. Simas now works for President Obama.

Notice anyone who’s missing?

That would be Doug Rubin, former Patrick chief of staff and current lobbyist/Herald columnist. And – face! – Rubin has a column in the same edition of the Herald, right alongside a second Herald DiMasi trial piece that doesn’t mention Doug.

The hardworking staff has already questioned why Rubin is in the news pages of the Herald rather than on the op-ed page.

Now we’re questioning why Rubin is out of the news pages.
