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.
The party has already made 42 gains and is averaging 26 per cent of the vote in those areas where it stood.
Lib Dems pushed into seventh place as Labour wins in David Miliband's old constituency.
Those now calling for a Tory-UKIP pact should consider how AV could have prevented a divided right.
