and well well well, what do we have here?

March 28-30, 2016: FOX News Wisconsin Poll

Hillary 49%
Trump: 35%

Hillary+14 in March 2016

in contrast to....Biden+5 in January 2020? LOL.

Also if you go the "it's different this time because Trump is an incumbent" route, then take a look at how undecideds often broke to Obama in 2012, and how many broke to Scott Walker relative to some polls in 2018

Frankly Fox News polls lost all their credibility with their IN-Sen 2018 and MO-Sen 2018 polls

Not to be rude, but you have a habit of trying to discredit pollsters when their numbers aren't great for Trump. Its pretty transparent at this point.
