Former Secretary of State Gen. Colin Powell is breaking party lines and backing Joe Biden for President.

On Sunday, the former Bush administration official told CNN he’d be voting for Biden, saying he “cannot in any way support President Trump this year”. 

Trump responded to Powell’s endorsement on Twitter, calling the retired General a “real stiff” who “was very responsible for getting us into the disastrous Middle East Wars”.

Are you surprised by Powell’s endorsement?  How much weight will it hold with Republicans?
