How can you want to vote lib dems? The only reason why they’ve become more popular is because Clegg has tried to distance himself from the other two parties, making out that they are both the same. This is not true and there are stark differences and they both have much more experience than the lib dems.
Clegg is attempting to gain votes from the least educated shall I say, those who if they like what they see will vote for him. They don’t care about policies and will vote like they would for x-factor. It’s those people that are giving him the boost in the polls.
