Who is considered the leaders of American Jews today?

This past Shabbos was the Lubavitcher rebbe's yartzeit and it got me thinking. 30 years ago America had big well known leaders such as Menachem Mendel Shneerson, Moshe Feinstein, and Joseph Soloveitchik. Other countries today, Israel has Ovadia Yosef and Yosef Eliashiv, Britain has Jonathan Sacks. There doesn't seem to be anyone like that in America anymore.

Who would be considered among the leaders today? Joseph Telushkin? Yehuda Krinsky? Dovid Feinstein? What do you guys think?
