They did that this year too! It's not just something they've done in the past. They gave millions of dollars to far-right candidates in the primaries, hoping that the candidate would knock the serious contender out of the race, and then they could beat the far-right candidate in the final election. It's devious, and apparently sometimes effective, but does raise a lot of questions and kind of overshadows this whole "we only take the high road" image they've tried to cultivate.
