Howard Dean...Bad Speculation?

Howard Dean, MD, speculated that Donald Trump's recurrent snorting during the First Presidential Debate might be secondary to cocaine use.  Potentially correct speculation without real evidence.  President Obama not being a citizen of the USA as cultivated by the Donald for years was potentially correct without real evidence.  So Donald, as President Obama responded, it is your obligation as a Presidential candidate to provide the nation with documented lab results from drug screening of your blood and urine.  Don't need to test your crap...we already know it is BS!
