Ed Balls’s secret: he doesn’t care whether his tax plan makes sense

There were a million people who voted Labour in the 2005 general election but not in 2010, when the party fell from a 66 majority to 48 seats behind the Tories. Thanks to the Lib Dems’ spiteful rejection of boundary changes that would have helped their coalition partners, the 2015 poll is already rigged in Labour’s favour by about 30 seats, so the number of floaters who have to be won over to give Miliband and Balls a working majority is likely to be well down in six digits rather than seven.
