They will remember that 1.5 million of their contemporaries are claiming income support because their pensions are so low. That a further million are believed to be entitled to income support but not claiming it, and living in poverty. That 7 million pensioners do not receive sufficient income to pay income tax, and that year on year their plight will get worse.
They will remember whose policies over the past 18 years have brought this about. They will surely vote accordingly.
