There's always plenty to chat about with Kady O'Malley.

On Wednesdays, CBCNews.ca's Politics blogger convenes a "people's caucus" to discuss and debate the issues of the week.

Featured today:

• Conservative Senator Mike Duffy is one of three Senators under fire as Senators are audited and asked to produce documents over a discrepancy in billing for living expenses. In his case, documents suggest he isn't registered as a resident in the province he represents in the Senate – Prince Edward Island – and that may contravene the rules. If he isn't really living on the Island, should he be allowed to keep one of PEI's four seats?
• The Conservative Party admitted Wednesday that it was behind robocalls received in Saskatchewan criticizing proposed riding boundary changes as not conforming to "Saskatchewan values." Tory MPs registered their beefs with the electoral commission's proposals as far back as last summer. But the party's recent use of robocalls has reignited the controversy over when and how automated phone campaigns are used for partisan purposes. Were any rules broken here?
• Plus: Did you take note of last night's "take note" debate on the conflict in Mali? If you didn't, you weren't alone. Only a handful of MPs from each party attended and even fewer spoke. The prime minister, his cabinet and Opposition Leader Tom Mulcair (who requested it in the first place) all took a pass on the opportunity to outline their policy views for the historical record. So, did it accomplish anything?
