COTTonLINE readers who don't find numbers inherently frightening will recognize each of those four increases as non-trivial. All four are in the 8-10% range, if given to hyperbole one might call that yuuge.
- Men. Trump was at 50% approval in March as compared to 42% approval in February.
- Young voters. In February, just 1 in 5 voters aged 18-34 approved of how Trump was handling the job. In March, that number increased to 30%.
- Middle-aged voters. Trump's gains among the young(ish) were one-upped by his showing among those between 35 and 49 years old, where he gained 9 points in approval in a month.
- College graduates: A group that has long been resistant to Trump had the biggest change of heart toward him between February and March: A 10-point swing.
Reading between the lines, I believe we can assume the poll did not show Trump's approval level dropping dramatically with any recognizable group. CNN certainly would have reported any drop found.
Cillizza attributes the increases to the recent tax cut; I believe credit can also be given to record low unemployment. Democrats should especially worry about nos. 2 and 4.
Meanwhile, writing at Hot Air with tongue firmly in cheek, Andrew Malcolm can't imagine what outré concatenation of factors has caused this bounce in optimism since late 2016.
