In a brief but interesting article for
The Hill, Mark Mellman cites a few figures that show Republicans tend to change their views and values in order to “follow the leader” during this election season. For instance, two polls show that 83-84% of Republicans now give their support to Trump, whereas last year a third of Republicans said they wouldn't support Trump if he were the nominee.
Another highly informative example:
In 2011, just 36 percent of Republicans believed someone “who commits an immoral act in their personal life can still behave ethically ... in their public office,” according to a PRRI Brookings poll. By October of this year, with Trump’s immorality being trumpeted everywhere, 70 percent of Republicans were distinguishing between politicians’ private and public lives — double the number five years ago.
Here Democrats’ views also evolved, but their level of agreement with this notion rose by a far lesser 12 points.

So perhaps there is difference between Democrats and Republicans in their partisan allegiance?
