@Quetzal is being a meanie pants and only letting the liberals talk about this, which I think would make for an interesting discussion.
For those who supported or voted for Trump, whether enthusiastically or holding your nose, at what point would you regret voting or supporting Trump?
What is the deal-breaker for you? Do you have a deal-breaker?
I never voted Trump, because I'm in Britain. So I have some excuse if it all goes pear-shaped haha. For me, my main reason from last year for preferring a Trump win over Clinton was always foreign policy. As a Brit that was really most of what I was concerned about. Trump's Secretary of State pick has been encouraging in terms of warmer relations with Russia, so it looks like he's serious about changing the neocon policies of the past few decades.
However if Trump decides to continue with reckless and idealistic foreign interventions to topple regimes, not being in the interest of his country, then that would have removed my initial and main reason for supporting him, and I will no longer be able to see why I should continue to do so.
