Carl Beijer:

What Trump is showing us, however, is that even if you win a short-term incremental victory, you can still end up with nothing in the end. You can engage in years of modest pragmatic compromise climate change diplomacy and find yourself right back where you started a decade later; you can pass "achievable" business-friendly health care legislation on the assumption that this will engineer some kind of universal coverage down the road, and then have it gutted as soon as the opposition takes power.
