From a Conservative blogger who covered Harper's celebration, which apparently had an introduction by John Baird.
The sign held by the guy on the right reads "John Baird, what are you doing for Nortel retirees?"
For all the Tories talk about hard-working Canadians, calling Ottawa West-Nepean families who have been let down by John Baird and his lack of leadership for the riding "pathetic" shows the real face of the Harper government represented by Baird.
