What is happening in both the House of Commons and the Senate at the moment represents a serious enough threat to our democracy that we require remedial efforts in real time, far in advance of whatever constitutional refinements to these institutions that might lie in the future. Our focus should be upon the selection process for Senators, at least in the interim.
Much like I can veto my best friend from buying a skirt I know she'll never wear, the Senate can veto parliamentary legislation as it sees fit. In fact, in the past, this veto power has been used pretty haphazardly, so why didn't the Senate veto Bill C-10? Perhaps it is because there is no pressure from Conservative ministers to kill the bill.
My wife comments that I am one of nature's pessimists. I don't deny that people will sometimes act kindly. I just don't expect it. Linda is very different. She sees the best in people, makes the widest allowance for human failings, and is always ready to believe in the possibility of change and improvement.
