I say that as somebody who grew up in Sheffield Hallam, and lives & works nearby. It's a very affluent and traditionally small c conservative constituency where there is still a fair bit of hostility to Labour due largely to how they run the local council.

Clegg has a huge majority, and even after all he's done he should be able to hold onto the seat. Even if it does meanrunning as a surrogate Tory.

I should also mention that I've known the Labour candidate Oliver Coppard since childhood and if truth be told, I don't rate him either!

His antics and betrayals may, however, cause a lot of LibDem defeats elsewhere - unfortunately in many places by Tories.

...is local election results since Clegg jumped in bed with David Cameron back in 2010.

The Lib Dem vote at Council elections since 2010 has held up in Clegg's constituency, whereas most other places locally it's collapsed. I myself haven't seen a single Lib Dem leaflet since 2011. Before that they were a regular occurance.

Not entirely surprising, although it will reinforce the perception that Clegg is little more then a surrogate Tory.

I must also point out that John Harthman is hardly the most persuasive of Tories. I remember him addressing our sixth form in 1997 and it was pretty excruciating.

A Con UKIP coalition gov't would be a very bad thing for the UK. Hopefully Cameron says no to them as a coalition partner.

....is that at very worst UKIP would only win about 7 seats, and even then most of them would be taken off the Conservatives. They are sure of at least 1 seat but beyond that?

The bad news is that UKIP are the party that most Tories would want to go into coalition with, and as you say that would be a total disaster.

Beyond that, the Tories might also want to go into Coalition with Northern Ireland's DUP.

And the Lib Dems have proved weak coalition partners, so another Tory/Lib Dem coalition would still be acceptable to many Tory voters.

I couldn't say that Clegg should retain his seat with as much confidence were it not for the local council results in Sheffield Hallam since 2010.

Mind you, by the same token the Lib Dems are not standing a single a single candidate in council elections just over the border in Derbyshire where I live. The decline of the Lib Dems round here outside of Sheffield Hallam has been quite pronounced.
