UKIP's success in the Clacton by-election has worried the traditional parties in one of the biggest battlegrounds of the next General Election.
The leafy Tory seat of Warrington South has a reputation for being a political bellwether, having voted for the winning party in every election with the exception of one.
But the rise of Nigel Farage has the candidates in the Cheshire seat fearing a result may be even closer.
The current Conservative MP, David Mowat, accepts that UKIP could pull vital votes away from him in May 2015.
"The electorate gave a message to the political classes that they need to be listened to and I agree with that," he said.
"But I don't think UKIP would regard this as one of their target seats - they could do damage here and that could have unintended consequences."
The "unintended consequences", say the Conservatives, are that a vote for UKIP could allow Labour to make gains.
The Labour candidate, Nick Bent, is hopeful: "The rise of UKIP does worry me," he told Sky News.
"I am worried that there are still an awful lot of people floating along with UKIP. I think they will take more votes away from the Conservatives than they will from Labour and that could help us."
In the Mulberry Arms, UKIP's James Ashington - a lifelong Conservative councillor until he defected some years ago - sips from a small brandy glass and smiles.
"The idea that we're taking votes only from Conservatives is nonsense. We're taking large number of votes from Labour, too, and I think the same will happen in May," he said.
"I am not sure whether we will win here but I think we will do some damage to the other parties.
"People have very real concerns about jobs, immigration and the traditional parties."
