Age dynamics are set to have a crucial impact on this year's election. In particular, there is evidence of very strong alignment between young voters and Labour, and between older voters and National. It seems that age issues, and generational politics have become politicised along partisan lines to a highly unusual degree. Youth, who have been somewhat absent from recent elections, appear to be re-awakening. But it's not clear yet whether this will produce any sort of "youthquake".
Of course, forecasts and speculations about a possible youthquake have been in motion for a many months, especially following the surge of young people voting in the UK, and the fact that they appear to have voted overwhelmingly for Jeremy Corbyn's Labour Party.
