From Pat Buchanan's May 14 syndicated column (emphasis added):

Indeed, of the last seven justices nominated by Democrats JFK, LBJ, Bill Clinton and Barack Obama, one was black, Marshall; one was Puerto Rican, Sonia Sotomayor. The other five were Jews: Arthur Goldberg, Abe Fortas, Ruth Bader Ginsberg, Stephen Breyer and Elena Kagan.

If Kagan is confirmed, Jews, who represent less than 2 percent of the U.S. population, will have 33 percent of the Supreme Court seats.

Is this the Democrats' idea of diversity?

But while leaders in the black community may be upset, the folks who look more like the real targets of liberal bias are white Protestants and Catholics, who still constitute well over half of the U.S. population.

Not in living memory has a Democratic president nominated an Irish, Italian or Polish Catholic, though these ethnic communities once gave the party its greatest victories in the cities and states of the North.

What happened to the party of the Daleys, Rizzos and Rostenkowskis?

And not in nearly half a century has a Democratic president nominated a white Protestant or white Catholic man or woman.

[...]

If Kagan is confirmed, the Court will consist of three Jews and six Catholics (who represent not quite a fourth of the country), but not a single Protestant, though Protestants remain half the nation and our founding faith.
