I think that if number of EO's were actually the reason to object to a presidency the (black) president with the fewest of them in recent memory wouldn't be the target of an article attacking his.
Why no articles about having to destroy the Bush legacy for the same reason? Probably because it isn't a reason but just an excuse to bash Obama again.
I don't see why. I'm pointing out a fact which does distinguish him from other presidents and which might be a reason why he is being attacked, since the facts show there's no reason to do so for the reasons claimed in the article in the OP. Maybe others could come up with other reasons why he was singled out.
I had to stop arguing with GOP types about Obama. The sad truth is that they hate Obama so much that it simply does not matter what Obama did. Whatever he did, it needed to be opposed. In fact, even when Obama tried to pass things the GOP agreed with during Bush or Clinton they opposed Obama simply because Obama proposed it.
During Obama's term, we witnessed an unprecedented level of obstructionism from the GOP.
Was it due to Racism?
I don't know. Maybe, maybe not. All I know is that the reason for the GOP's pathological hatred of Obama is not logical given what Bush II, Clinton, Bush, and Reagan have done. Obama is well within "the norm" of presidential behavior and actions (adjusting for changing times and technology). There is plenty that I hate that Obama did, however, when I look at how he conducted himself as a whole and how he interacted with other States, he was a pretty good President, definitely better than Bush II and in the same League as Clinton and Reagan.
However, the GOP's support of Trump is something that I cannot fathom. To think, the party of Reagan actually is on record arguing that Russia is a great ally of the US while simultaneously trying to block an investigation into whether or not there was undue influence on the American System of Government by the Russians...
Ultimately I blame Conservative Talk Radio.
Back in the 90s I shared an office with 2 office mates. We each took turns listening to the radio in 1-hour increments. I had a co-worker who loved Rush Limbaugh and for 1 hour per day, I listened to Rush Limbaugh. The amount and degree of brain washing that Alt-Right talk radio does day in and day out was/is frightening. Everyday he'd make an outlandish claim, get great ratings, and then the next day he'd outdo what he did the day before. Rinse and repeat this formula over decades and it is no wonder why the GOP sees Democrats as Godless-Soulless-Communist-Kitten-killers that want to eat your children
I mean this with all sincerity. If I were the leader of ISIS, I'd make sure no one messed with the US. You see, the only time the US can unite is when we have an external enemy. Otherwise, we tear ourselves to pieces. This fight between the Dems and the GOP is doing more harm to the country than ISIS every could.
