You posted that Trump won’t get a bounce from Pence. There is anecdotal evidence that Trump is already getting a bounce. Of course no one knows for sure how it will settle out until actual polls are conducted. None have been as yet since Trump and Pence only announced formally this morning. You may be proved dead wrong, and Trump may get a nice bounce out of his selection. It’s still too soon to know for certain.
The Republican nominee’s share of support has risen to 42% in the latest survey, putting him one point ahead of his Democratic challenger Hillary Clinton. Trump’s support is up from 40% in the previous round of interviews while Hillary Clinton’s support held firm at 41%.For the record - Turns out I was correct.
Unfortunately the controversy bounce was self inflicted so the other part of my prediction (Trump would get a bounce from the protesters) that you ignored ("how do I know?") didn't happen. So you can be happy about that. I guess.
