If you'd like a quick overview of polls which favor, and don't favor, the reelection of the President, Power Line's Paul Mirengoff has got the story for you. There is good news and bad news, as you might expect.
Rasmussen has Trump at 51% approval, which Mirengoff assures us is what Obama had at this point before his reelection. Trump’s ratings on a Fox News poll and a The Hill survey are like those of Bush II when he won not just reelection but also the popular vote. That's the good news.
If you insist on seeing the bad news, you'll have to go read Mirengoff's column. Other polls aren't so positive.
