I think that moving to Canada is more of an emotional reaction than a rational one. I didn't vote for Trump nor am I very supportive about it, but the world soldiers on. I think people toy with the idea, then look into it, and find they like their home country still. Even if the current leaders are not their favorite. People also forget that, although congress is the same political party as Trump, he has successfully alienated his party mates and they hopefully will keep his power in check. The president doesn't have as much power as people think he has. Congress controls spending, budgets, economy, interest rates, new laws, immigration, etc. Congress also has to approve going to war. We are very fortunate that we have a branch of government that can do serious damage control. Trump also does not appear to have the support of the military either, so trying anything using them against the best interests of the country would be difficult.
I think the worry is that those who wanted Hillary in power are just going to give up. I hope that people like Bernie Sanders and Gary Johnson will continue fighting for what they believe in. I hope that a women still run for office. I hope that we as a country can still stand for common decency and world peace. We are more than one elected official.
