If people had not voted Conservative you would now have Ed Milliband & his joke party and be even more broken.
Next time you will have Respect as well to deal with .. they are going make a big impact, as in hitting the fan.
The Lib Dems wont peel off, they will disappear into the ether. After the next election the Monster Raving Looney Party will have more supporters than the Lib Dems which is why Clegg is hanging on to his fifteen minutes, a Lib Dem he may be, thick he aint.
You seem to be suggesting the electorate have to vote for Labour or the Tories because they are the only two parties that have a chance of winning. I must point out that the only reason a party wins is because people vote for them. I accept, reluctantly that the next election will be a competition between Labour and the Tories as all post war elections in this country have been. However, I think the electorate are getting restless, Labour has changed for the worse (IMO) and as for the Tories, well at least we have a modicum of comfort in fact that we know what the Tories do, they don't change.
It's time for change which is why I've joined UKIP, I don't for a minute think they have all the answers but to simply vote Lab/Con 'as usual' is not the answer, we need change and any change would be better than no change.
It is not racist to be concerned about immigration.
