Maj Gen (Ret) John Batiste has is now on the record in support of Democratic control of Congress:
"The best thing that can happen right now is for one or both of our houses to go Democratic so we can have some oversight," [...] Batiste describes himself as a "lifelong Republican." But now, he said, "It is time for a change."
Though the Massa campaign has used Batiste's written and on-air critiques of Kuhl in advertisements and debates, Batiste has not officially endorsed Massa or any other candidate as far as I know.
