I know I have blogged before on "It's so close here" and the misleading leaflets from the LibDems, such as the one which claims that only the LibDems could beat the Tories in last month's European election in Maidstone with the famous bar graph of a convenient election result. The statistics used there were the numbers of councillors on Maidstone Borough Council rather than numbers of votes.
They also like to distort the size of the bars so that the result looks closer than it really is, but just look at this bar chart that I discovered while throwing out the election stuff.
The key ploy remains the same, us or them politics. In this one they try to make out the Tory threat is greater than it really is.
