What would 1920s US immigration quotas have looked like if Hughes would have won in 1916 and the Democrats would have subsequently won both the US Presidency and the US Congress in the 1920s? On the one hand, the American public was more anti-immigration in the 1920s than it was in the 1910s and earlier. On the flip side, though, I suspect that Democrats might have relied a bit more on ethnic votes relative to Republicans and thus might have been somewhat more sympathetic to the pro-immigrant cause. Do we see something like the 1921 Emergency Quota Act, but with a higher quota ceiling (say, 5% instead of 3%) and without it being replaced later on by quotas based on the 1890 US Census rather than on the 1910 US Census, which disproportionately favored Germanics and Irish at the expense of Southern and Eastern Europeans?
