Taken at face value this would imply that the legal cases are really bad, effectively wasting court time. This in turn implies that the judges would have handed down a frivolous litigation judgement with associated penalties for the plaintiffs. But if this has happened, I'vd not seen it reported in the news. Why?
Perhaps it depends where in the media you go looking for news on this:
I've read that more than two dozen lawsuits have been thrown out by the courts. We also have a conservative judge, Matthew Brann, in the state of Pennsylvannia, 'accusing' Trumps legal team of trying to:
disenfranchise almost seven million voters ... [by using] strained legal arguments without merit and speculative accusations ... unsupported by evidence.
This sounds like Brann is accusing Trumps team not only of 'frivolity', but something much worse.
And I have also heard on the BBC, that one prominent republican, the ex-Governor of New Jersey, Chris Christie, has called Trumps law team, 'a national embarrassment.'
