Worse than the Canadian Senate?

Historian David Silbey defends the US Senate against the charge that it is “the least democratic legislative chamber in any developed nation.” 

He provides comparisons to upper houses in several countries, but seems unaware (perhaps fortunately for Canadian sensibilities) of the Canadian Senate.  Still he fudges a bit, I think, on the question of whether the upper houses he compares, like the British House of Lords, wield actual power, as the American Senate certainly does.  The saving grace of our Canadian upper house is that it has no power -- which is as the confederation makers intended and carefully provided for.
