It would be absurd for the candidate who has real money and runs a real campaign to drop out in favor of someone who has neither.
That makes Weiland look even worse
What does it say about Weiland if he has "real money" and is running a "real campaign" (I'm pretty sure Pressler is too, but whatever) and yet people are still flocking to the person who, according to you, has neither. It sounds to me like Weiland has every advantage over Pressler and yet he's such a weak candidate that all he's managing to do is potentially play spoiler for what would otherwise be a safe Democratic hold in everything but name. On the other hand, if Pressler has surged into second place and is only down by about 3% with a little over three weeks left until the election despite having almost no money and little in the way of campaign infrastructure, imagine how much more he'd be able to do if he had the money and infrastructure that Weiland seems to have squandered
More importantly, the SurveyUSA poll showed that a Weiland-Rounds head-to-head leaving both candidates tied with 47% while Pressler led 54-39% when he was placed in a head-to-head with Rounds. Clearly Pressler is the stronger candidate and has a far better chance of winning than Weiland does in the race as it stands right now. If Pressler drops out, it becomes a tossup in a state where a majority of the undecideds will probably back the Republican. If Weiland drops out, it becomes a safe Democratic hold in everything but name (and we get a Senator from South Dakota who is more liberal than most of the Senate Democratic caucus). This isn't complicated
