According to the Office for National Statistics average, (median), household income recovered last year back to the 2008, (pre banking crisis), levels.

So yes you are right about incomes but I don't understand why that would encourage voters to support someone like Trump that wants to repeal universal healthcare laws, tighten up the welfare support such as it is, hasn't paid tax for 8 years and so on . . . . it sounds like turkeys voting for Christmas.
