Regular readers might recall that Marc Garneau, Canada’s first astronaut and former president of the Canadian Space Agency, left the CSA in 2005 to run for the House of Commons in a riding in Quebec west of Montreal. That run for office didn’t work out well, as he failed to unseat the incumbent there. Garneau, though, is planning another shot for office, and is upbeat about his prospects. Garneau is the Liberal Party candidate for the open seat in Westmount-Ville Marie, a riding in Montreal where a by-election will be announced by late July. While the campaign has not formally started, Garneau is already on the trail, making a number of public appearances. Unlike his last campaign, Garneau enjoys a high degree of support in the riding, according to an article in a local paper; he also has the advantage of succeeding another Liberal MP, Lucienne Robillard, whose retirement in January created the vacancy Garneau is trying to fill.
