What makes you think Hillary would have carried forward the nomination?
I don’t. I’m just saying that Obama brought up Garland, supposedly a ‘moderate’, to make Hillary look more moderate. I suspect she would have picked a radical (like Kagan) if she had won, but the only name out for consideration by the Dems was Garland at election time. I do think he was also named to try to get support from the Republicans who hated Trump....the Republican elites, who might have crossed over to Hillary.
