The main "effect" of Hispanic immigration isn't in partisan politics - but in the balkanization of the U.S.!
Name any other ethnic/religious/linguistic group getting remotely so much government service - particularly "bilingual education" - in some language other than English in the U.S.! "Bilingual education" is almost never about any other language but Spanish.
And let's be honest about the reality of Kalifornia - where the vast majority of Hispanic immigrants go. It is an incipient Mexican-culture nation - as "reconquista" proponents favor. That has never happened with Swedes in Minnesota or Italians in New York. High continuing Hispanic immigration will eventually result in Kalifornia seceding - with great benefits to conservatives in the other 49 states, as it will forever end the Democreeps' having any viability as a "national" party.

People so often over look this unprecedented change to the American culture. The frog in a pot of water that is rising in temperature applies well here. To make matters worse we have the spectacle of the 2 parties groveling on the ground before Hispanics while all the other constituencies...like the productive taxpaying AMERICANS that make this country go are ignored. This is past disgusting.
