Roberts was nominated and confirmed
years before Ted Cruz joined the senate. Yours is typical of Donald Trump’s “vetted” talking points.
And nobody confirmed John Roberts on the basis of expecting him to uphold Obamacare, which didn’t even exist then. You’d need one hell of a crystal ball to predict Roberts would vote with the Dems on that one while voting conservative on literally everything else including same-sex marriage.
Senators Obama and Biden voted against confirming Roberts. I believe to my core that Roberts voted to uphold obamacare to avoid any appearance of vindictiveness. Virtually no one saw it coming. The man is an abject coward.
