From the Washington Post:

For the first time since his own presidency, George H.W. Bush is planning to stay silent in the race for the Oval Office — and the younger former president Bush plans to stay silent as well.
Bush 41, who enthusiastically endorsed every Republican nominee for the last five election cycles, will stay out of the campaign process this time. He does not have plans to endorse presumptive GOP nominee Donald Trump, spokesman Jim McGrath told The Texas Tribune. […]
Bush 43, meanwhile, “does not plan to participate in or comment on the presidential campaign,” according to his personal aide, Freddy Ford.

I hope other Republican leaders who share the convictions of these two former presidents will have the same courage to act upon them.
