Slavery?  Who mentioned slavery?  

"...Portuguese ran slaves ships from Africa to the United Sates (sic)..."   Portuguese slave ships to the "United Sates (sic)"  Really?  Did they serve sausages to the crew?

"Little Brown Brothers"  There's that white elitist attitude again, what next "The white man's burden"?

Perhaps Ted Cruz was right about New York attitudes.  In any event fact checking by geriatric political candidates local and national is painfully inadequate.
