From his Wikipedia:

"Murphy won a Progressive Conservative nomination in 1975. However, he abandoned it due to lack of funds. Instead, Murphy went to work as special assistant to PC leader and Premier Frank Moores.[4]

He then switched parties in the 1980s and served two years as chief researcher for the provincial Liberal caucus before running for provincial office twice, as a Liberal."

Sucks to suck.

"Murphy argued that climate change is "a sub-branch of climate politics". He criticized former American Vice President Al Gore's opposition to the Alberta oil sands and in a 2013 column, called the industry "a dazzling and profitable engineering endeavor of which all Canadians should be proud"."

Rex can absolutely get fucked, what a sellout shitbag.
