The spin coming from the Left that debates don’t really matter is factually correct but that doesn’t take into account the world witnessing an obvious mental decline. The Wall Street Journal just published an article that states an anonymous White House aid claiming Biden often show significant mental impairment in the evening, while WSJ is typically considered reputable they probably should not be reporting anonymous sources on something of this gravity. Another report about Biden struggling during a recent meeting with Zelenskyy, again unconfirmed.
The world witnessed what appeared to be significant mental impairment and the American people need to know if it’s an issue. I think the best course of action would be some medical testing someplace like John’s Hopkins, Walter Reed or similar. This isn’t an issue you can simply gloss over and say he has a strong Cabinet and advisors that can carry the weight if needed.
