EU scare stories

It looks like the Netherlands might be having a referedum over the
mini-Constitution because the dutch political class are starting to crank up the fear about it:

If the Dutch again vote no to a European constitution, the Netherlands may have to leave the EU, according to junior foreign affairs minister Frans Timmermans

Exactly the same things, and worse, where said before the Netherlands' first rejection of the EU Constitution, and what happened? Nothing. The Netherlands is still in the EU with exactly the same position as before (that is as the largest per capita net contributor). The EU wouldn't let such a juicy prize slip out of it's grip so easily. If the EU is so good why don't they make a positive case for it rather than relying on emotional appeals about avoiding rejection or not getting some, never specified, future good. Why not make a positive case based on what the EU actually does, such as the CAP and CFP (which account for the majority of the budget)? Oh, there isn't one.
