Sure. This article is dishonestly implying that the odds referred to are from Augur. They’re not. They are from electionbettingodds.com, which gets them from BetFair (a centralized betting site).
If INVALID was a tradeable outcome (as it will be in Augur v2), then, based on historical performance, it would be ahead of most of these candidates. This is bad because having to play the Augur “meta-game” destroys the generally slim advantage you may have in such markets.
