...Never before in my lifetime has either political party been led by a man with such an unusual combination of—from a national security perspective, anyway—terrifying liabilities. Individually, each would be grounds for concern. In combination with one another and as embodied in a single political figure of extreme charisma and proven attractiveness to a significant swath of the electorate, they are a toxic brew that I have no doubt makes this country less secure. They do this, I suspect, even if Trump is not ultimately elected President but merely becomes the Republican nominee.
