RCP shows Trump in the lead, but RCP also uses only polls that still use the outdated ‘landline dominant’ methodologies. Landline dominant polls have been consistently off by wide margins in races from Israel to Great Britain to Kentucky.
Polling is subject to be in error sometimes large errors. Yes polling techniques change
and have to be adapted to by all polling companies. For sure you are likely to get a
different demographic with online versus live calls thus the results will differ.
We’ll see how this turns out before much longer. Take care.
