OK, but 52% is a pretty scary number. I'm still curious for a source on the statement that "most of them voted for him for reasons other than the promise of a Muslim ban".
If big numbers did vote for him on that reason then there's a cancer running deep in USA's society that trying to brush under the rug isn't really going to help.
In a two-party system, few people agree with every policy in someone's platform. I voted for Clinton but disagreed with many of her views and actions. Oftentimes people are voting based on a single very important issue or for the lesser of two evils.
I'm curious why you think supporting a ban like this is a "cancer"? It's heavy-handed and misguided, but religion is ideology. People see heinous acts worldwide perpetrated in the name of Islam. Some Muslims have extremely regressive beliefs on women's rights, gay rights, personal freedoms like drinking alcohol or even making loans that make even the staunchest Bible thumper look progressive. They see countries with larger Muslim immigrant populations like France in constant disarray, with little integration and once peaceful neighborhoods lit on fire. Even people with no initial ties to terrorism read up on this ideology online and commit lone wolf attacks.
So why do we want these people coming in? Maybe we have a principles-based belief in religious freedom and don't want to appear discriminatory. There are some more secular or Westernized Muslims who can live peacefully and contribute to our society. Helping refugees will help save innocent lives and undermine ISIS. Those are all great reasons, but it's disingenuous to pretend they come at zero cost. Some people do this analysis and say it's worth it, and others disagree. A sovereign state has a right to its borders and admitting immigrants who advance its interests.
I don't support the ban, namely for the reasons I gave above, but it's completely understandable why someone would. It doesn't make them a bigot or evil, just scared and perhaps lacking in empathy. The hardcore left does itself no favors in this regard, constantly parroting the "religion of peace" line and pretending there are no reasonable reasons to oppose immigration that they need to argue against.
It makes them bigoted or evil because people likely said the exact same things about their ancestors (unless they are descended from native americans or the original british colonists)
His mix of indepedent and democratic voters pulled largely from the 12% of democrats and 31% of independents that support the ban. Again, it was literally his platform.
