There is only one issue here.
All parties, I believe, are striving for, more or less, the same objectives:
They all are in favour of a healthy, well-educated population.
They are all in favour of helping the less fortunate.
They all agree that the environment should be protected for ourselves and our children.
They all believe that immigration is generally a positive and will continue.
They all believe that crime is bad and should be discouraged.
They are all in favour of a strong economy that can pay for social programs.
They all agree that, internationally, Canada should contribute to the betterment of the world.
What differs, of course, is the methods of achieving these objectives. Some party's ideas will be more successful than others.
I submit, therefore, that there is only one major pressing issue in this campaign. It is one of trust, integrity and principles. I will not rehash the findings of Gomrey, but any party, regardless of political stripe, MUST be punished if found to be breaching the public trust. A short list from recent Canadian history include the NDP in BC for 'Bingogate', the Socreds in BC for VanderZalm's dealings with personal business, and the Progressive Conservative party in Saskatchewan for expense account fraud.
To support a party guilty of criminal activity is to condone it. I care not how sorry, contrite and willing to change they are......they were caught, and they must be punished. Remember that many of those who were involved were likely never brought to task, and are still working within the great Liberal machine.
On principle alone, I could never support the current Liberal party. They have breached the public trust, and despite a one million dollar payback, still have over fourty million unaccounted for. Perhaps, once they have sat in the back benches for a term or two, I may revisit this, depending on whether or not they have evicted the cancer that currently inflicts their party.
Despite having voted Liberal in the past (1988 - I didn't like the Conservate policy on nuclear subs) I shall be voting Conservative this time.
