Sensible was the wrong choice of words. What I meant was that they are actually voting for a workable alternative. Good or bad, Labour would be able to be in charge of the country should they win an election tomorrow. The same cannot be said for the Lib Dems. It's completely ridiculous to suggest that the Lib Dems are a credible alternative to the two leading parties and so those who vote for them can't really be taken seriously. I currently disagree with Labour policies, but I can respect those who vote for them and I cant say I wouldn't vote for them in the future. Lib Dems? No chance.
