Bernie Sanders threw his support behind presumptive Democratic presidential nominee Hillary Clinton at a boisterous but at times awkward rally here Tuesday, more than a month after Clinton effectively clinched the nomination. Both candidates touted the need to come together to defeat Republican Donald Trump, and both offered effusive praise for the other — words not uttered during the bruising Democratic primaries. But their body language was stiff, and it was clear from shouts of “We love you Bernie!” that not everyone who supported Sanders was ready to move on.
