Wilson endorsed the B.C. Liberals on Sunday night in an effort to boost the B.C. Liberals' political fortunes.
A video was posted to YouTube showing Wilson urging voters to join him and reminding them about the NDP government's track record during the 1990s.
"After 20 years, I believe that all of us who were so excited at the B.C. Liberal breakthrough in 1991, but who left the party in 1993, and those of us who don't feel comfortable at the prospect of an Adrian Dix government, [should] come home."
Political scientist Hamish Telford with the University of the Fraser Valley says Wilson's address could give the B.C. Liberals a small boost at the polls. Telford also says Wilson's past, which saw him leave the Liberals to form his own party and then jump to the NDP, may weaken the power of his endorsement.
Overall, Telford says the endorsement may only help with older voters who remember Wilson and the 1990s — people in their 40s and 50s.
"That's important because when you look at the opinion polls. The Liberals poll much better with voters over 50. Over 55, there is very much a dead heat between the Liberals and the NDP," he says
Telford also says the older demographic is especially important to reach, since older voters are more likely than younger votes to cast their ballots.
