Let me guess. Because C-Span is an organ of the government, and Savage often says those three words the government won’t tolerate: Borders; language; culture.
This is a common misconception. If it were an organ of government, we would have seen more of President Bush over his term. When ex42 was in office, C-Span was saturated with him and his wife. With President Bush, they barely show his major speeches.
C-Span is paid for by the Cable TV owners of America. Think Ted Turner when you wonder why they program the way that they do. President Bush's replays are often listed like TBA or just skipped in the listings. You have to guess that a missed time period might be him.
