Michael Ignatieff scored an endorsement that was almost out of this world just as first-ballot voting was about to begin.
Marc Garneau, Canada's first astronaut, pledged his support for Ignatieff, calling him the "candidate of renewal" and the one "best positioned" to beat Prime Minister Stephen Harper.
A space shuttle rocketed Garneau into orbit in October, 1984 and into fame as the first Canadian to ever fly in space. He went on to fly twice more in space. Unfortunately Garneau didn't have much luck in his more earthly exploits into politics -- he ran unsuccessfully in Quebec's Vaudreuil-Soulanges riding in the January election.
But he's been active in the Liberal Party and took part in Thursday night's tribute to former Prime Minister Paul Martin at the leadership convention here.
Bob Rae collected his own high-profile endorsement today from former cabinet minister and Fredericton MP Andy Scott. Scott held several cabinet posts when Liberals held power, most recently serving as the Minister of Indian Affairs and Northern Development.
