Liberal Finance Minister

If the Liberals form the next government, who will be the next Finance Minister?
Ralph Goodale: 15%
Scott Brison: 15%
Joyce Murray: 10%
Dominic LeBlanc: 5%
Someone Else: 55%

There are several candidates for Finance Minister if the Liberals form the government.  Ralph Goodale has been Finance Minister before, and is currently Deputy Leader.  He also represents an area (Saskatchewan) where the Liberals are relatively weak.  Scott Brison is the current Finance critic.  Joyce Murray was the most successful challenger to Trudeau in the last leadership contest, and is the National Defence critic.  Dominic LeBlanc is House Leader.

With this sort of question, I like to allocate a fair proportion to the field; there are a lot of potential candidates who I have not listed, including those who are not currently MPs.  This is especially true for the Liberals with their relatively small base of current MPs.
