Spineless politicians
It's the people who are spinless, as it's very clear a large number, very likely a majority, will vote to stay in.
Not so much spineless as thick!
A large proportion, possibly the majority, of the electorate are too stupid for their own good because they take as gospel everything they are told by their favourite politicians.
I, too, worry that we'll vote to stay in, even if we are given the opportunity of a referendum, which is by no means on the cards. We shall then continue (through our own stupidity) to be $hit on by the EU, simply because we are seen as an easy target.
