A 13-point lead for Hillary Clinton on July 14 has vanished in two weeks with Donald Trump now leading in the polls by 1 point. This is clearly unacceptable to the establishment and so Reuters/Ipsos is taking matters into its own hands… and ‘tweaking’ its polling methodology.
Trump has seen a huge bounce since Comey and the convention as Clinton’s bounce was marginal…
Something has to be done.. So Reuters “tweaked” their algos…
In a presidential campaign notable for its negativity, the option of “Neither” candidate appears to be an appealing alternative, at least to participants in the Reuters/Ipsos opinion poll.
Many voters on both sides have been ambivalent in their support for Democratic nominee Hillary Clinton and Republican nominee Donald Trump, complicating the task of the pollsters trying to track the race.
That sentiment may help explain an apparent skew that recently emerged in the Reuters/Ipsos poll results. Given the choice, a relatively large group of voters opted for “Neither/Other” candidate compared with other major polls, leading to an underreporting of several percentage points for one or other of the two major contenders at times in the race.
As a result, Reuters/Ipsos is amending the wording of the choice and eliminating the word “Neither,” bringing the option in line with other polls.
