### Comment:
Its not a surprise that border crossing spiked under trump given that he was VERY public about preventing the crossings on the border. Anyone wanting to come over, was going to come ASAP to get in before they closed the border. 
  
 The real question is the difference before and after the tariff threat.

### REPLY:
Well no, if your thesis is correct you'd want to normalize the crossings. If more today, less tomorrow you'd want to average out.  
  
 Still remains that the bulk of the reduction in crossings happened under Obama (so far, at least). And that was with no destructive tarrfis or bigoted rhetoric.
