Is obama a god who cannot be criticized according to liberals?

Rubbish, Obama was criticised plenty by liberals when he was in power. Here is Fox News back in 2014 delighting in telling it's viewers how some liberals were unhappy and critical of the unprecedented number of illegal immigrants Obama was deporting. 

Fox News even promoted a name for Obama "Deporter in Chief"  https://www.foxnews.com/politics/deporter-in-chief...

Here is another example where Nancy Pelosi opposed the TTP trade deal.  https://www.huffingtonpost.co.uk/entry/nancy-pelos...

Another example is the number of Democrats who voted against the gun control measures Obama tried to implement.  https://abcnews.go.com/Politics/15-democrats-helpe...

There were many such instances during Obama's presidency, over trade and tax deals, over the Patriot Act, etc. etc., The difference is that when Democrats publicly disagreed with or opposed Obama he did not sack them, go on Twitter calling them every nasty name he could think of or put them on a "to destroy list"

How wonderful it will be to have a president again who is enough of a man to take opposition and people in his own party who are willing to stand up and say "I disagree" and elected officials brave enough to tell their party leader they think they are wrong.

No but thanks for asking this stupid question.

He is not criticized because virtually everyone feels sorry for him.  He was set up for failure when he was forced into the Presidency and we all knew that he was being used by the Deep State.  

Nope, anyone can criticize him.  But garbage like he wasn't eligible for office steps over the line of criticism to sheer stupidity or racism.  Now compare that to trump, who will launch a personal attack on a private citizen for saying he isn't pretty. I find it hysterical that conservative believe liberals view Obama as the messiah, yet they are will to overlook any defect in trump's character or behavior. 

I've seen many leftists criticize Obama.

As far as people on the right go, I haven't seen much criticism of Obama that didn't involve lies or some sort of racial jab

History rates President Obama very high, history is already rating Trump the lowest. A single termer and impeached at that. That is the Trump legacy. Bigly Loser!

You misspelled "Trump" and "conservatives".

according to several "regulars" here, you can criticized him all you want.....

...but the only reason anyone would ever criticize him is because of racism....

Of course not.  Liberals and his voters criticized him a lot.  What we did not tolerate was racism aimed at him, and we know the difference between racism and honest disagreement.

As a liberal it is very hard to find something to criticize him for. My main criticism is that he look so long to endorse Joe Biden.
