With five days until Election Day, Rasmussen Reports’ Thursday edition of its daily presidential approval rating survey reports that 52% of likely voters approve of President Donald Trump’s job performance, whereas 47% disapprove.

The survey, which was sponsored by the conservative news site Liberty Nation, also found that 40% “strongly approve” while 40% “strongly disapprove.”

“Daily tracking results,” according to Rasmussen, “are collected via telephone surveys of 500 likely voters per night and reported on a three-day rolling average basis.”

In addition to that, “The margin of sampling error for the full sample of 1,500 Likely Voters is +/- 2.5 percentage points with a 95% level of confidence,” its states.

On the other hand, Gallup, who released their most recent study on Thursday too, instead found his rating to be at 46%. Notably, however, it found that 52% of American adults approved of Trump’s handling of the economy, his strongest subject area. This survey polled 1,018 American adults between October 16 to 27, and it has a 4-point margin of error.

As for why the ended up with different results could be for a whole cornucopia of reasons.

The most likely of these reasons is the fact that both entities employ different strategies than each other in their respective surveys. While Rasmussen only polls likely voters in its daily approval rating surveys, Gallup polls Americans adults in a broader sense.

Their differing political leanings could also be a major factor. Historically, while Gallup generally falls in the political center, though some would argue that it skews more liberal, Rasmussen tends to skew more conservative.

Whatever the true answer might be, the real survey happens Tuesday, November 3.
