As it was for the "Tartan Tories", the real test for UKIP is not whether it can take votes off the Conservatives but whether it can build a broader long-term coalition.
Rather than aping UKIP, the party should focus on the cost of fuel, the cost of housing, job security and the cost of travel.
UKIP is the British version of a Europe-wide rejection of mainstream, established politics.
With Cameron's party on 27% and Farage's on 17%, the gap between them is now smaller than the gap between Labour and the Tories.
The stubborn survival of Clegg may prove to be more significant than the noisy arrival of Farage.
The timing of the move is a political gift to Ed Miliband.
After confirming that he will stand for a seat, the UKIP leader is likely to have his eye on Boston and Skegness.
Five months after the Conservative whip was suspended from the MP for Bedfordshire, it has still not been restored.
UKIP won the day, but not because of Europe, a Tory MP may well defect and parliament will be hung after 2015.
