Bc's confusing politics

I believe that many voters in BC are faced with a difficult choice in the next provincial elections. We have a choice from among three political parties, the ruling Liberal party, the NDP and the  untested Conservative party. The polls show that the Liberal party is no longer the popular choice of the majority of voters. The NDP are  by far the leaders in the polls. The Conservatives are led by a man of unknown quality formerly active in the Federal government.
Should I vote for the NDP who brought economic disaster during their previous terms in office. Is Adrian Dix  any better than previous leaders of the NDP with a policy of tax and spend? Is he a radical social democrat? Can Christie Clark regain the confidence of BC voters?
This is the dilemma that I face as a voter in the next Provincial elections.
