|Some straws for you to clutch at|
It gets better though - 86k people who voted Labour in 2010 and nearly 500k who voted Lib Dems also intend to vote UKIP at the next election which, when added to the 900k+ votes UKIP got in its own right in 2010, gives UKIP potentially 2.8m votes.
People who intend to vote UKIP find a Tory government marginally more palatable than the alternative by a ratio of 6:4. This type of question in a poll produces nonsense results though because it forces you to pick a party that you don't want. These same people also prefer the Cameron/Osbourne gruesome twosome to the Labour or Lib Dem alternative but again this produces nonsense results because none of them have a clue.
Most people saying they intend to vote for UKIP think immigration is more important than the EU and want a return to common sense and politicians listening to what they want rather than spinning bland politically correct nonsense. UKIP is, of course, the natural home for such people.
