First, on Sunday, the Observer released its Ipsos Mori poll, which showed strong support for the Conservatives's approach to the economy and recorded a seventeen point lead for David Cameron's party.
In contrast, the Independent's ComRes poll suggests that the Tories' lead has been trimmed to nine points, with Labour up 5% since its last survey. An odd result given that Alistair Darling's Pre Budget Report was greeted, in general, with scepticism by the media.
Under the Observer's piece, Sir Robert Worcester, founder of MORI, offers something of a corrective to sensational newspaper headlines about changing poll leads.
Nine of the past 10 polls show the Conservatives at or over the 40% level, where they have been since July. Three leads were 17%, three below 10%. Not one varied in the Tory share by more than 3% from the 40% average.
It's worth noting that UK Polling Report, which is generally offers fairly circumspect analysis, is of the opinion that the ComRes version is most likely a rogue poll.
