It's poor PR for Western democracy to see the election results challenged in such a sordid manner. Putin, Xi Jinping, Alexander Lukashenko must be particuarly happy to hear of Trump's legal actions.
it's also creating a chasm between the Trump family and the Republican Party. If Ivanka hoped to run for President then Trump's killed this ambition off for many years...but knowing the average age of US presidents, this may not be an issue!
