There have been 7 confirmed left-handed presidents of the United States of America with the latest being Barrack Obama. Who will be the next?

"Leftie" here referring strictly to handedness. Add answers, since it's hard to figure out which political figures are left-handed. If an answer is mistaken and they turn out not to be left-handed and but do become president (or assume the presidency and do not sign legislation with their left hand), they will not resolve.

Hand used for writing will be used as the determining factor. In order to qualify as ambidextrous (and NOT a leftie) there has to be evidence the person regularly uses both hands to write, using different hands for different stuff is just common (you're not special).

Resolves "N/A" if the United States no longer has a central executive figure, or ceases to exist.
