Last night on CBC Radio's As It Happens show, host Carol Off interrogated Stephen Harper's parliamentary secretary about a little-discussed aspect of the mess in the Senate.
Off repeatedly asked Paul Callandra if the Conservative Party of Canada would take responsibility for an expenses scandal that threatens the Senate careers of former broadcasters Mike Duffy and Pamela Wallin.
Callandra responded by condemning the two senators for violating the rules.
According to a Globe and Mail article earlier this year, Duffy campaigned for 17 Conservative candidates in the 2011 election campaign, including Harper.
Duffy also reportedly claimed per diems from the Senate while doing political work for the governing party.
Wallin helped Conservative candidates in Saskatchewan. But there was no evidence, according to the Globe and Mail, that she billed taxpayers for these activities.
The Conservatives captured 166 seats, 13 more than necessary to win a majority.
In addition, Duffy and Wallin were exceedingly useful on the party's fundraising circuit, a point emphasized by Off.
Keep in mind that neither Duffy nor Wallin comes to the table with clean hands after charging taxpayers massive sums in expenses in violation of Senate rules.
It's difficult to feel much sympathy for them in light of this.
But it doesn't take away from the central point made on As It Happens: the Conservatives benefited enormously from the two of them, and now the prime minister is more than prepared to throw them overboard now that he has his majority government.
