As most conservative Jews will tell you, not much will change because most liberal Jews are completely secular Jews who don't care about religion or Israel. If you look at the list of political issues liberal Jews care about from your article, you'll see none of it has to do with the Jewish faith. They're pro-abortion, affirmative action, immigration, anti-zionist, etc - most of their positions are either in direct contrast with the faith (not their faith, as they don't have faith) or have little or nothing to do with it.
Now if the rampant anti-semitism taking hold in America's Universities starts to really impact their secular Jewish children or spreads beyond academia, then they may have a problem but otherwise, I don't see them becoming less liberal.
