"小土豆" is party leader. A party critic has extra money from party, and party leader even.
Opposition party (NDP) leader salary is PM salary, opposition party has its own SHADOW cabinets, also pay exactly like official party cabinets.
In the last election, Michael Idiot screw up Liberal party hence it is "Angry Muclair" who now lives in Stoneaway (official party leader residence) but not "小土豆".
"小土豆" has his shot in 2015 election.
Actually "小土豆" is making more money on giving speeches, to U, charitable organization, etc etc.
