Raise a point about the inconsistency in people's values and how political allegiance can cause people to overlook behaviors or statements they would normally deem unacceptable.
But does anyone ever share 100% of your values?  I saw a video of someone walking through the streets of NYC asking people who claimed to be Hillary voters who said a particular quote, Hillary or Trump, then a somewhat shocking quote was read.  Almost everyone attributed it to Trump, yet they were Hillary quotes.  I take those things with a grain of salt because you never know how they are edited, but Hillary was anti-gay marriage until it became politically expedient for her in the past couple of years.  Hillary's campaign staff started the Obama birther controversy.  Hillary called black men "Super Predators".  I could go on.  Don't mistake this as me suggesting Trump has never done similarly stupid things, but are they really "values" if people are willing to set them aside to support a political party?
