The paradox of politics and policy in redistributing income

With political ideology with respect to the income distribution measured by proxy as the fraction of conservative coalition victories, it is found that over the period 1961–1984 the degree of conservative coalition strength is positively associated with changes in inequality, holding the effects of unemployment and inflation constant.A natural question is why don't the low income types vote in candidates who will consistently redistribute income in their favor? The result of such a political process would be a downward trend in income inequality. In point of fact, there is no evidence whatsoever of any trend in income equality over the period. The answer to both questions may be that Tullock (1983, 1986) is on to something. If the middle class voters transfer gains back and forth, the poor can't gain and they don't, then the distribution should be stable and is.
