74 percent, surveyed on Saturday said party officials should continue to support Trump
This is actually an awful poll for Trump. 26% of respondents fell in line of not supporting him or no opinion.
Again, as a reminder, somewhere around 95% of Republicans supported Romney, 92% supported McCain. Trump peaked a short while back at 83%.
This means his own party support is crashing around him.
..and this is an extreme poll to in that it asks the question about the party supporting him, not just if they would hold their own nose. So he is probably slipping even further there..
In other words, trends are working against him like an avalanche.
