So the 51% in this poll saying that 100,000 Syrian refugees this year is too many...that sounds plausible to me.
Granted, Obama wanted to increase the number of refugees admitted, but the last fiscal year we admitted 100,000 refugees was 1995. We didn't let in even 40,000 refugees from the Middle East as a whole during any Obama fiscal year. So apparently Trump could brag about "reducing" the number of Syrian refugees to 50,000 and people would believe him.
