I was gonna title this "And here I sit so patiently waiting to find out what price you have to pay to get out of going through all these things twice" and then write "Stuck inside of America with the fascism blues again" here, but I'm not sure if that comes off like gloating and that's honestly the last thing I want to do this morning.
The policies are extremely popular and universal. Doesn't really matter in a politicalcampaign if you struggle to achieve those ends. Trying is important and failing gives you ammunition against those who oppose extremely popular policies for next campaign.
The bottom line is that the average person isn't listening for anything besides "how is the candidate going to help me because I feel like I'm drowning". The right scapegoats something and promises to fix your problems by hurting the scapegoat (immigrants, minorities, socialists, whatever). This is a lie, but it's just as, if not more, direct of a solution so some voters will support them.
