Fox News hasnt been friendly territory for former Vice President Joe Biden , but many of the conservative networks personalities offered praise for the Democratic presidential candidates acceptance speech on Thursday night.

Although President Donald Trump has tried to portray Biden as not all there and mentally shot as well as a captive of the far left, Fox News anchor Chris Wallace said the president will have a tough time with that argument after Bidens speech at the Democratic National Convention.

I thought that he blew a hole, a big hole, in that characterization, Wallace said . It seems to me that after tonight, Donald Trump is going to have to run against a candidate, not a caricature.

Fellow Fox News personality Bret Baier was similarly effusive about Bidens performance.

Hes not known for his public speaking, but this Ive been seeing him speak on the stump many, many times was the best hes been as far as his delivery, Baier said.

Fox News host Dana Perino said Biden hit a home run in the bottom of the ninth.

He had pace, rhythm, energy, emotion and delivery, she said . I think if he looks back, hes gonna say, thats probably the best speech of his life.

Even Fox News contributor Karl Rove offered praise, saying Biden portrayed himself as a unifier.

He did so very effectively and if I were a Republican strategist in the Trump campaign, Id be worried about how long and how effectively he carries that theme forward, Rove said. Because thats the thing that will keep the swing voters in his camp if they are in his camp or bring them to him.
