Dems campaigned mainly on the lies that Republicans were going to take away your social security, Medicare and health care, especially for pre-existing conditions. People who only see the propaganda press never even heard that these claims were all lies.
In my area, Democrats campaigned on the fact that the GOP has had full control of the Federal government for two years and has accomplished almost nothing. I voted a straight Republican ticket for the first time in my life, but I couldn’t argue with that.
