Obviously, Donald Trump won't be impeached or removed so long as the Republicans hold even one House of Congress. And even should they lose both in November of 2018, launching an impeachment - as the Republicans discovered with Bill Clinton - is very dangerous to the impeaching party. Unless you have a highly credible set of extremely damning facts, you turn a constitutional crisis into a political crisis. You rally potential supporters of the impeached president to him. You make his base bigger. So I imagine that he is likely to serve out the full term.
David FrumThe system has evolved to protect parties from people like Donald Trump. It really is true that people without well-established public records, without proven capability in public service, without tested beliefs and at least apparently under the influence of a foreign power, such people are screened out by major parties.
David FrumI want people to understand that, look, we're in a period of democratic deficit, democratic recession. There are fewer democracies in the world today than in 2005, and in many of the countries that are still technically democracies, we're seeing a reduction in the rule of law. And that's especially true in Central Europe, but it's also true of places like South Africa, the Philippines.
