Grimsby is fucked, Mitchell is that old rightwing Labour that is not far off UKIP on some social issues, or at least not far off what some former Labour voters seem to have abandoned the party to find elsewhere, Labour did noting visible really for the area between 97 and 2010 except preside over further long term decline, and the council (North East Lincolnshire) has not been Labour since it was formed IIRCWith an incumbent Tory government and a national election campaign going on? Nah.
I don't think UKIP will win it, but a very close second is extremely likely
