That's not what most polls say, and I guarantee that's not what polls will say in the next few days.
But think about this .. even if that poll is true, what does that say when a party celebrates and welcomes poll numbers in the low 40's?
i urge you to look at the progress of the polarization of the american electorate over the last 20 years. 40% is quickly becoming the new 50%.
secondly something you always seem to forget, obama was in the thirties a year out from his election in 2012. He still won. Approval ratings aren't a direct correlation to electoral strength. For example there could be some conservatives that "don't approve" of trump but when giving the option they still will vote him over the democratic candidate. Trumps floor seems mostly established at this point, and 2 years is still a long time in politics. You act like it's impossible for him to go back up. But if you actually look at his approval ratings over the last two years it's quite the seesaw.

Thank you for the clarity.
