Surely either she or her PR people would have recognized that someone would eventually point out that she answered the question re Paul Revere incorrectly, so they must have planned for her response for when the time came. But why not fess up with a "Yes. Sorry. I meant 'the British are coming'. My bad." Even her twisting of historical events in the second interview was off. I was half expecting her to twist her initial response with "But you have to remember that we were British back then, so yes, Paul Revere did warn the British. The British colonists that is." Historically correct? More so than what she said in the interview, but she probably thought that the Declaration of Independence was already signed prior to the Battles of Lexington and Concord.
But hey. Isn't that what most politicians are good at? Covering up mistakes and pretending they never happened?
