After Gordon Brown declined to call a snap General Election in 2007, his popularity and Labour's poll numbers slipped. At times in 2008 and 2009 Labour were trailing the Conservatives by around 20% in some opinion polls. However, as 2010 began, Labour rose in the polls, while the Tories slipped.
The campaign itself was fairly dull, with Brown keeping to his message of "we need to stay the course", and Cameron saying that Britain "cannot afford another five years of Labour". Clegg didn't have much of an impact, although some have speculated that if televised debates had taken place, he would have come across better than Brown and Cameron, and hence may have received a poll bounce. By election day, the UKPollingReport "Poll of Polls" gave the figures: Conservatives - 37%, Labour - 34%, Liberal Democrats - 19%.
By the end of the BBC's Election Night 2010 programme, David Dimbleby stated that he was amazed at how similar it was to 1992, with an unpopular government upsetting the predictions of the pollsters and pundits and winning a fourth consecutive term in office. Even Labour's majority (27) was quite similar to the 1992 Conservative majority (21).
Anyway, the above was mainly aimed at political "newbies". My question is: What if the Tories had emerged as the largest party, and then proceeded to form a coalition with Nick Clegg's Liberal Democrats?
