If the historical drift right with age is true (I've never believed so, but it's a popular theory) they could return to influence. That's the main fear.

Top line is, the drift to conservatism as we age no longer holds. The thread goes into more detail as it’s a bit nuanced.
But as one LNP strategist said dejectedly on national television during the LNP wipeout “you can make new conservatives if they have nothing to conserve”. If the status quo doesn’t serve the majority of voters why would they do anything but vote to change it.
