I think that is an unfair comparison. Being articulate does not does not imply any other quality than just being articulate.

Back in the day I thought Obama was amazing. He was articulate and considered in his manner of speech. Then we hearing about the drone strikes with heavy collateral damage. And then Snowden came out and told us how Obama administration had put in place all the necessary infrastructure for a surveillance state. And then he put in place Title XI and kangaroo courts at Universities to completely undermine the core tenet of our legal system "Innocent until proven guilty".

Articulate does not equal morality or justice or fairness. It certainly did not with Obama.
