Are the Unions damaging Labour's chance of election in 2015?

First topic message reminder :

The multitude of examples of disgraceful behaviour by Trade Unions over the past year have really started to show them up as the evil bully-boys they are.

Latest example being the vicious targeting of the wives and children of Ineos managers:

Question is, will this start to hurt Labour's chances of election in 2015?

Clearly formerly 'Red' Ed is concerned as he's taken steps to distance himself from both their antics and the Unions themselves, surely all this negativity will have to bite at some point? This could be the last thing Labour's already dwindling opinion poll leads need - could 2014 be the year of the turning point re public opinion or the main two parties??

Yeh, my overall opinion hasn't changed much. Think Labour will take a slim seats victory but won't have sufficient to form a parliament (basically a bit like 2010 in reverse). It then comes down to a horse trade as to who gets kinged.

Clegg and DC are natural bedfellows, but he may get deposed by 2015. Which could push the Liberals into Labour's arms.
