I read somewhere that these silly media brouhahas have a lifetime of about 3 days. Seems about right.
The evidence of these polls seems to be that it’s better to fight tooth and nail for those three days than to just ride it out.
Though that may depend upon specific circumstances.
If the media didn’t have these particular polls they keep a close eye on the public and surely knew the trend.
Any other politician would have slinked under a rock. Trump knows how to show how it is done.
