I really stopped reading after this. Since when is this a stereotype? Just because you dislike Obama does not mean that every black person running is "stereotypically charismatic" and has the same platform.
Since the Democratic Party runs on racial (and various and sundry other grouping) identity politics. This is as contrasted to the "stereotypical enraged black candidate" in the mold of Al Sharpton. That blueprint fails on the national level but is extremely effective in liberal enclaves.
These are merely trends in campaigns. There's a huge amount of black political campaign theory out there, as a political science minor I just happen to be interested.
So no, it has nothing to do with disliking Obama and everything to do with it being a standard issue campaign blueprint. The blueprint varies slightly with each candidate but is fundamentally the same.
Though I have to say, for people whose political gatherings invariably involve breaking out into sessions like "Black caucus" and "LBGT caucus," liberals are surprised far too easily that there might be stereotypical campaign styles based on exploiting these traits. Obama's candidacy was textbook in its "if there is opposition to Obama's policies it is because he is black" spin on every issue. By the end of the primaries they were calling Clinton voters racist. It worked so well they forgot it breaks down once they are the incumbent.
If you need a specific breakdown of the blueprint, I can provide below.
"Charismatic Black Candidate Blueprint":
1. Our candidate is historic because they are going to be the first/second/whatever black <desired office>.
1b. If the current office holder is black, claim that you are trying to keep the hope alive and continue to give voice to minorities (this works even if the current officeholder is of the opposing party).
2. Our candidate thus represents something new on the political scene inherent in their blackness.
3. Therefore our rhetoric will be entirely based on bringing new hope and change to the old (presumably angry WASP) establisment.
4. Never get into specifics if possible, because then defense via 5. becomes more difficult. Frame yourself always as a "change" candidate. You will get votes based on how many people you inspire with your charisma.
5. To deflect criticism, claim racism. Drum up the "return to the old ways of the <state capital or Washington depending on office> establishment" line.
EDIT: I should also note that this blueprint is generally only effective for either a) a challenger to the current incumbent or b) a replacement for an incumbent of the same party making their first foray into a major elected office.
These are blueprints because they work. There is no doubt Obama and Deval Patrick executed this blueprint perfectly. This is how politics operate. There are also blueprints that Conservatives and Republicans use all the time, it's just as a matter of course they don't usually involve exploiting race or sexual orientation (religion is more common, though.) Huckabee's "Chrisitan Leader" platform in the 2008 Presidential race is a great example.
If you want to have some fun, try and see if you can guess the blueprints of your gubernatorial candidates!
