The pro-EU argument.

Everytime there is a big UKIP success, the europhiles, especially in the Libderal Democrats and Labour, cry on about the need to make the "pro-European" argument.
We're in the middle of a European Election campaign. Neither party, nor the Tories, even dare run a campaign on the issue of the EU. A consensus of silence, if you will, from the three pro-EU parties.
UKIP's campaign is about nothing-but the EU issue. Quite telling, no?
