St-Denis said her decision was based on the Liberals' social policy and job-creation strategies as reasons for the jump, as well as the NDP pulling support for the mission in Libya in its final weeks.
St-Denis says she didn't believe she'd be elected when she let her name stand as an NDP candidate, but that it wasn't unusual for her to run for the party because she'd worked for them for 10 years.
But she said she's been pondering the jump almost since the May 2, 2011, election.
"It’s been six months that I’ve been reflecting and discussing," she said.
"I wasn't named a critic and I was sat in the back row because of my last name, which starts with S, so I had lots of time to look and listen to everyone," St-Denis said
These are, at best, odd reasons to make this kind of thumb your nose at your contituents move.
But I still believe in love, hope and optimism so I will refrain from any more critical comments of St-Denis.
She added: "St-Denis says she didn't believe she'd be elected when she let her name stand as an NDP candidate, but that it wasn't unusual for her to run for the party because she'd worked for them for 10 years."
The 71-year-old's battle with cancer just may have caused further reflection that perhaps her last kick at life's can could be played out in a less ignominious situation. But perhaps only a septuagenarian can fully appreciate that.
