Bernie Sanders declared, from very early in his campaign that, should he be the loser he would support the Democratic nominee. He has held out from doing so for as long as he could, while attempting to have some of his campaign issues included in the party platform (wobbly though that platform may prove to be, in time), and to edge Hillary Clinton leftward in her stances.
I watched the whole joint Hillary/Bernie campaign speeches from New Hampshire this morning, felt for him, and for his legion of supporters.
I hope some benefit accrues to Bernie for his efforts on behalf of the Democrats, I hope he will attain some prominent position in the next administration - he certainly deserves it. I shall always remain a fan, as I had been for years, long before the 2016 campaign began. I shall continue to trust his judgment and integrity, whatever happens from now on.
Hillary Clinton's speech was fair to Bernie, and for that much I'm happy.
