Since Trump won the most votes in the history of the Republican primaries, and 10s of thousand see his rallies everyday "29R" is much unrealistic. 37% to 38% is more likely. Hillary is lucky to get a few hundred to see her highness. I don't even recall it be this low (29R) since I've been looking at polls, and Indies are too high by about 8%.
self ID polls (this low 29R) or self ID during exit polls
The only purpose of these”polls” is to position the Democrats to steal votes for Hillary. And the media can proclaim, “All the “polls” showed her leading by such and such margin. And the Republican Party, as usual, will remain absolutely mute.
