Some others' "two cents":
Rick Perry withdrew and endorsed Newt Gingrich and is raising money for him.
Herman Cain withdrew and in time endorsed Newt Gingrich and is campaigning with him.
Michele Bachmann withdrew and has withheld her endorsement (the Party has her reelection fate in their hands) but she wasn’t so reticent at a 2008 Minnesota townhall.
[3:00] Michele Bachmann profusely praising Newt in this 2008 townhall introduction …”This is real! We love you here. We love you!”
;)
She also told him to stop using her voice in his ads since she has not endorsed him.
