Sorry to ruin your mudslinging, but if you read the second sentence of the linked study, you'll see the American voters' choice of president has nothing to do with this:

Not true. The article asserts that immigration policy is a big driver of "stay rates" for immigrants.
Also, I did not assert that either party is "good" on immigration. The US should relax restrictions and allow many more immigrants to enter/study/work/live.
If we really want growth, fully open borders would double world GDP.
Sorry to ruin your ruining, but if you read past the abstract and look at the data, you'll see it tends to correlate with whether a democrat or republican is in office. Immigration policy is also mentioned in the discussion.
