I always thought the main counter was to remind folks that the GOPers claim to love the Constitution but they dislike the very gov't it set up. To be against the US Gov't is to be against the Constitution and unpatriotic.
Then to remind folks that large corporations are immensely wealthy and powerful and only the Gov't is able to check their malign influences, including greed, amorality, pollution and other externalities, and these days lack of patriotism.
Drifting on a tangent, the Dems also can't let the GOP constantly bash the media. And Trump calling the media the enemy of the people should be a major theme. It's a signpost on the road to fascism. The media is a key watchdog and cog in the system, and undermining factual information paves the way for misinformation and outright lies in which Trump specializes. Undermining the media weakens and undermines America. He needs to be called out for that.
