Here is how the final votes were cast:
House of Representatives:
- Democrats: Y=152; N=96 (63% against passage)
- Republicans: Y=138; N=42 (25% against)
- Democrats: Y=37; N=27 (73% against)
- Republicans: Y=27; N=6 (22% against)
To be sure, most of the opposition in the Democratic ranks came from southerners, but the voting record clearly debunks claims by the Left that Republicans have a "race problem".
If either party needs to address its historical position on race, these facts suggest it should be the Democrats.
