Anybody But Conservative strategic voting can be summed up as:
1.
If Cons have no chance of
winning, vote for whomever you want
2.
If Cons are sure to win,
vote for whomever you want
3.
If Cons are close to being
beaten by only 1 party, vote for that party
4. If in a 3-4 way race, decide & vote for who has best chance to
defeat the Cons
The problem is mostly with points 1 & 4.
