If the Republican candidate loses, Donald Trump intends to try to overturn the election result. What sits behind his position is a rare and unusual fight over a candidate's name. A lawsuit mounted at Trump's instruction has already drawn a stream of critics. Opponents read the move as an attempt to dictate the terms under which an election can be settled. Critics of the push also say the decision should belong to voters, not to the president. It remains to be seen how any court views a challenge built on grounds like these. For now the legal filing is pending, and Trump has made clear he will keep pressing if the vote goes the wrong way for his candidate.
