It's not feelings.
It is 100% "evidence" that relieving college debt only impacts 1 of 4 Americans. It's "evidence" that Trump's support comes from the other 75% and would be invigorated to vote more because of taxing them to cover people they already envy and hate. Now, you are taking their money to pay for people who make more.
You can dream all you like but this is a hanging curve for Trump.
As to "evidence" about healthcare, the GOP is already attacking that.
You can tie the two together for nine figures of "Trump cut your taxes, increased employment. Now, Bernie/Warren PROMISE to raise your taxes and TAKE away your insurance."
Regardless of how true that may or may not be, a ubiquitous set of advertising it for several months would re-elect Trump.
Public Option For All would do very well and not give the GOP an easy target. In the end, the results would be the same.
