After his first announcement which implies he is still running, nothing. If he still intends to drop out at some point, which may never happen, I don’t think it will be until after the debates. He wants national exposure first. He’s worked hard to get a podium at the debates. He is not just going to throw it away.
RE: He wants national exposure first.
I personally do not think that Vivek has a chance of winning the nomination and HE KNOWS IT.
Like Herman Cain, Pete Buttigieg, Dr. Ben Carson, etc., they are running for NAME RECOGNITION. At best, they are angling for appointment to head a department should Trump win. Even VP is a long shot.
