Trump's stamina attack on Clinton draws charges of gender bias. Republican nominee and his GOP backers have been leaning on stereotypes throughout the campaign.

The AP reports:

Donald Trump and his Republican allies say Hillary Clinton is weak, lacks stamina and doesn't look presidential.

Intent on undermining his Democratic rival, Trump and GOP backers are increasingly relying on rhetoric that academics and even some Republican strategists say has an undeniable edge focused on gender. His criticism of Clinton goes beyond "Crooked Hillary," and complaints about her use of a private email server as secretary of state and her foreign policy decisions.

Clinton, Trump said in a speech last week, "lacks the mental and physical stamina to take on ISIS and all the many adversaries we face."

The AP (Democrats-Hillary Clinton) is upset that people question the health of an elderly out of shape woman with health issues.
