is a nice chart. Folks should check the R-D split for the top 10, just for grins.
That's a fun top ten list

2. FORD, HAROLD E JR 60
3. BIDEN, JOSEPH R JR 56
4. WATERS, MAXINE 52
5. FRANK, BARNEY 51
6. LIEBERMAN, JOSEPH I 49
7. JONES, STEPHANIE TUBBS 47
8. CLYBURN, JAMES 45
9. BAYH, EVAN 42
10. MCDERMOTT, JIM 39
