Tulsi is the only candidate that has a snow balls chance in hell of defeating Trump. She refused to take the shot against Biden relative to the corruption of Biden’s son in the Ukraine. Thus she is also part of the coverup of corruption. She is also now political dead meat.
Yes, she has left Biden alone. Makes her look like part of the establishment she claims to be against.
Tulsi has no chance because she recognizes the corruption within the Democrat party. It is too corrupt for someone to defeat it overtly from within.
