Remember when Obama was president and the Tea Party “patriots” disrupted town hall meetings held by Democrats, which the Democrats didn’t run away from? Of course you don’t. Americans don’t remember anything. But that did happen, and Democrats lost in the midterms because they put up with the abuse that was based on right wing fantasy.
Now, we’re dealing with reality, and the GOP is running scared. So Republican strategy is to not meet with voters in their states and districts. They need to be severely punished in the midterms. If they’re not, it will show that the best way to deal with your constituents is to ignore them.
