Obama was not criticized for his religion because the leftys know that it is a sham and that it nicely aligns with their own ideas. Talk about hypocrisy.
There was some criticism on Obama's religiosity too coming from the left, usually in the form that he wasn't really that religious but used it to try and appeal to certain voters. Something, as mentioned, virtually every president has done in the last few decades.
I can't recall there being any criticism of Bush Jr's religiosity, however.
So attempting to merely paint this as a thing "lefty's" do, and only do to Republicans seems to be a false statement. What is happening in this instance, in regard to Trump, is the amusement of someone attempting the same, doing so with all the usual bravado Trump is known for, but then seemingly having failed to do enough homework in order to provide some basic questions.
If his favorite passages from the Bible were so personal that he couldn't be public about it, one has to wonder why he'd make a big deal that the Bible is his favorite book. Some of use merely find this
amusing. It's entirely possible Trump's favorite book really is the Bible and he really needed that to be known, and that his favorite parts of the Bible are just so personal he can't say them out loud. But, let's be honest here, at the very least that looks an awful lot like, "I wasn't prepared to have to back this up."
That said, I wouldn't be entirely surprised if, at some point in the nearish future, he does have a couple passages handy. And then, of course, more amusement.
I personally couldn't care less about Trump's religiosity, what religion he is, if any religion at all. I merely find this--again--amusing. Trump is a gold mine of unintentional hilarity.
