I think I've had the wrong leaflet from the Lib Dems. It says that "only the Lib Dems can beat Labour here now". I hope they realise that this is the Euro-elections, where the Lib Dems have never won a Welsh seat.
I was, however, comforted to see a chart showing the Lib Dems and Labour neck and neck in the polls and a big arrow saying "Can't win here" over Plaid. But in the seats that Plaid, Lib Dems and Labour all contested in the Wrecsam constituency, Plaid won both, Labour came second and the Lib Dems came a very poor third. OK, it was only two seats but that's what you can do with statistics.
A final point: Plaid is criticised for delivering "a poor deal" while in government in the Assembly. Wrecsam Council received 3.7% in the last settlement, one of the highest in Wales. Still, it's nice to get a mention.
