Do not obsess over every poll
Reading opinion polls is like checking your weight: there really is no point fretting over every minor daily fluctuation. Tomorrow the Tories may be one percent ahead, today one percent behind. The general trend is solid: both the major parties have been basically neck and neck for months.
Just because the Tories are ahead, this does not mean they are winning
This may seem like an odd thing to say, but due to the unfair and outdated boundary system, Labour would still probably get the most seats even if both parties received an equal number of votes. Or even if Labour got a few percentage points more. It is thought that the Tories would need to be at least five percent ahead in the polls fairly consistently to even stand a chance of becoming the largest party. They aren’t doing that currently.
Don’t get paranoid
True, the press are overwhelmingly Tory. Don’t let this fool you into thinking that no poll from either Ashcroft or The Sun or The Telegraph can be trusted though. There is no obvious bias in their polling.
Ignore betting odds
Betting odds seem to b being treated almost as seriously as opinion polls in this election. Treat these with caution. They are, after all, derived from people’s opinions on who will win and these are most likely ultimately shaped by the results of opinion poll anyway. That and the press. The suspicion that Labour is heading for defeat owes more to the anti-Labour feeling in the print media than to which party people say they are intending to vote for. In short, Labour is winning but many believe the newspapers who are telling them the opposite.
Watch out for electoral upsets
Beware! Opinion polls can be wrong too! There have thus far been two great post-war electoral upsets in 1970 and 1992. Both resulted in the Tories winning unexpectedly. Both were twenty two years apart. Twenty three years on from 1992, we are about due for another one!
