Voting does still influence a number of things, some of which have real impact on many people. I certainly haven’t said it is the only way to have an effect, or that it has nearly enough effect.
What I’ve said is as fewer and fewer people vote, it’s only played further to the interests of those who can afford to do the pre-selection. Voting for the least evil is not much restraint on them, sure, but giving them full control is even less.
