study Steven D. Levitt's schema on data he selected to prove his renditions of 'truce' in America ...e.g. "How Senators Vote? Disentangling the Role of Voter Preferences, Party Affiliation, and Senator Ideology" (Levitt, June 1996). - Appendix - estimated ideologies for Senators in Sample is interesting. Bob Dole scored 0 of the estimated ideology. Is that a coincident or Bob Dole is simply used as a fixed point on Levitt's scale? Also read in some place that Steven's great uncle wrote the famous "Rudolph the red nose raindeer..." song, which reminds me of this little piece on our national anthem which came about in 1931 different as what it stands later for many newcomers...
