Does Elphicke do his own graphics? Visually that 3.3% looks to be 40% of the way up his own column (if you'll excuse the expression).
In any case, last time round there was no BP, and UKIP's vote collapsed like a balloon in a pin factory. Were Farage to climb down off his own ego, remove his blinkers and do some strategic thinking he might see there's something in tactical voting, especially in leave constituencies with astute electorates, such as Dover.
If the current deal has passed or is still on the cards come the next GE, and Elphicke is still around, it shouldn't be difficult for the BP to nick his petard and hoist him with it.
