The lone exclusion to tonight's debate is Option Nationale leader Jean-Martin Aussant.

Hardline supporters say they'll flood social media to express thier displeasure with the decision to only go with the other four parties.

Some four-thousand party members are being encouraged to tweet and Facebook the party's soviergnist platform.

Aussant says his party is among tne most active with social media since
the election campaign began, that it's important to use all possible tools to get his party's message out.

Aussant lost a legal bid to be included in the debates.
