Please carefully re-read my post. The two presidents share a segment of the electorate - the people whom trumpet every political "victory" of their chosen idol and ignore their glaring and obvious shortcomings. To be clear, their "shortcomings" can be of differing degrees and magnitude, but the willingness of their respective voting blocks to defend them with little to no objectivity IS THE SAME. That is what they have in common.
President Obama, in stark contrast to his oratory skills, had a terrible, maybe the worst, "messaging" of any Administration in the modern era. What he was doing and why he was doing it (or not doing it) was an intellectual muddle. His second term was a merry-go-round of remarks, backtracks, and no action. He did a poor job of articulating a clear policy on Russia(Putin)/Syrian government, which ironically lead to their union and his isolation. President Obama had a fantastic manner and "looked good" in the office - he will probably end up a Reagan-esque character in the Democratic party, but let's face, he aided the financial recovery, killed bin Laden, got the Affordable Healthcare law passed and.... and... sang Amazing Grace...
