Strategic voting - part one

It seems likely that strategic voting is going to be a big part of the election, especially in B.C. where up to 10 seats could be in play next week.
Under our current, deeply flawed system, it's inevitable, if unpleasant, that people have to vote for a candidate that isn't their first choice in order to block a party they don't want to see in powe ror support one they do.
The problem is making the most effective choice given the lack of available information on what other voters are going to do.
The Tyee has poll results that could help in making a strategic choice. I'll point to other resources over the next few days.
