Carney stands by Gladu's crossing. Are his Liberals still liberal?

Prime Minister Mark Carney defends accepting former Conservative MP Marilyn Gladu into his caucus despite her past opposition to a host of Liberal policies and positions, saying crossers bring 'a series of perspectives and expertise that is aiding the country.' Liberal House leader Steven MacKinnon tells Power & Politics that the party has values that Gladu 'has to adhere to.' Plus, Sarnia Mayor Mike Bradley says he wants Carney to call a byelection in Gladu's riding so voters can confirm they really want a Liberal MP.
