All ballots should come with a "No vote" option. What would the difference be from just leaving it blank? Nothing, except that it would give uninformed people a box to tick so that they don't have to stray towards the more important ones.
With that said, his stated corollary (to vote against propositions by default) is unhelpful and perhaps harmful. Many ballot proposals are stupid. Some aren't. As a voter, if you don't have an informed opinion, the right move is to leave it blank. Don't vote. Leave the job to those who have done their homework.
The tact there being that party affiliation was more important than expressing their own choices, which isn't something that I understand in the slightest, especially as how centrist most candidates are.
In front of that, there's probably, "My parents were Republican. My family is Republican. My friends are Republican." And so on.
This isn't actually wrong, per se. It's a basic affirmation of trust in one's close network. Some people go to church without bothering to believe in God; they go because they've always gone and their parents go and their friends are there and they discuss the football game or whatever. They're passionate about things because all of their friends are passionate about it.
I rephrase that as "It is not good to have uninformed people voting." There are two ways to fix that: One is to work on the word "voting," the other is to work on the word "uninformed."
Uh, unjustified assertion ftw? Please tell me the rest of that paragraph isn't supposed to be the justification.
