> How many of the current US Senators and Representatives went to Ivy League schools? I'm not going to do the research to answer that, but I bet it's at least the majority, and probably the overwhelming majority.
You would lose your bet, especially in the House of Representatives, where less than one in six went to an Ivy League school. Just take a look at the Education column in https://en.wikipedia.org/wiki/List_of_current_members_of_the...
Among current Senators, I find that 29 = 12 (R) + 16 (D) + 1 (I) went to Ivy League Schools and 71 = 41 (R) + 29 (D) + 1 (I) didn't. Only one person in the leadership of the majority party (10 people, including the president of the Senate--himself not a Senator) went to an Ivy League school. Leadership is indicated by an ﹡ below.
