Subsidies, something Republicans dread unless it's public sector cash for them and their private sector corporate cronies.
This time launch a trade war, but hope impacted farmers stay "loyal." Encourage loyalty the Republican way; give up billions in subsidies, as if money can buy midterm election love. Do that while mouthing the same old stale platitudes, disdaining the thought of there being intelligence among their base. Just because money buys politician loyalty, why project that attitude to farmers with rectitude?
