GOP senator who bashed RNC convention parts ways with party again -- and lauds Kaine pick

Along with having a reputation for being "boring," another portrait of Virginia Sen. Tim Kaine -- Hillary Clinton's VP choice -- has emerged from those who have covered him and those who have worked him.

He a nice guy who doesn't seem to have an enemy in the world.

Appearing on The Rachel Maddow Show,  avid Hillary Clinton supporter, Minnesota Sen. Amy Klobuchar (D), as well as former NAACP exec Benjamin Jealous -- who supported Bernie Sanders -- both complimented Kaine for being a "good guy," although they parted ways on how much he would help the ticket.

On Twitter, Klouchar wrote, "Congrats to my good friend @timkaine on being @HillaryClinton's running mate. Longtime fighter for middle class families & born in St. Paul!"

New Jersey Sen. Cory Booker, also reportedly on Clinton short-listed tweeted a simple: "KAINE IS ABLE!!!"

While Clinton rival Bernie Sanders was quiet on the Twitter front -- after an evening of watching Donald Trump's acceptance speech -- Kaine received a thumbs up from Arizona Sen. Jeff Flake who wrote: "Trying to count the ways I hate @timkaine. Drawing a blank. Congrats to a good man and a good friend."

Earlier in the week, Flake took his party to task for their calling for the jailing of Clinton, writing: ".@HillaryClinton now belongs in prison? C'mon. We can make the case that she shouldn't be elected without jumping the shark."

Flake defended hammering his associates on medium.com writing, "“Republicans are not going to defeat Hillary Clinton in November by insisting that she belongs in prison any more than we defeated Barack Obama by pretending that he was born in Kenya. So let’s drop the references to orange pant suits and chants of ‘lock her up.’ These jokes and bromides may play well in rare venues and limited circles, but they cheapen the very real arguments that need to be made to the broader public against a Hillary Clinton presidency.”

Now he has failed to be a GOP attack dog on Kaine.
