Trump's wild claims test limits of Republican loyalty

President Donald Trump's wild and unsupported claims of voter fraud have emerged as a high-stakes Republican loyalty test that illustrates the tug of war likely to define the future of the GOP whether he wins or loses the presidency. There is a pervasive sense among current and former GOP officials that the president's behavior is irresponsible if not dangerous, but a divide has emerged between those influential Republicans willing to call him out publicly and those who aren't. Driving their calculus is an open acknowledgement that Trump's better-than-expected showing on Election Day ensures that he will remain the Republican Party's most powerful voice for years to come even if he loses.
