Not really...
Recent polls, like most polls of the last 6 months, suggest that the election will be very close. But I don't see where the seats will come from for the Tories to form another coalition (they have no chance of a majority and if they went with a minority government, who would vote through their issues?)
Clegg is polling badly in Hallam, so there's a good chance the Lib Dems will have a new leader after the next election. This throws things even more against the Tories.
A Labour minority government (with the SNP helping them vote through issues) seems most likely imo. But we shall see, it's all to play for whether red or blue.
