Bacco must be the most wearisome character ever commited to paper.
Yes, yes, a thousand times yes. She seems like she was written in as a dream president during the Bush years - not sure if she was supposed to be a (Hilary) Clinton or Obama analogue or a combination of both.
Her first appearance was in
A Time for War, A Time for Peace, which was published in 2004. Keith R.A. DeCandido would have written it, therefore, probably mostly in 2003. Barack Obama did not become nationally well-known until he delivered the keynote address at the 2004 Democratic National Convention. As such, it is ridiculous to claim that Bacco is based on President Obama.
Hillary Clinton and Nannietta Bacco have almost nothing in common other than being women, so I'm not sure why you'd equate the two.
KRAD has said that he based Bacco in part on former Texas Governor Anne Richardson, in part on the late Molly Ivins, but
mostly upon his late great-grandmother.
If they start making her less perfect in the Typhon Pact storylines, that'd be great. She's just such a perfect, awesome, dream of a president it's just obnoxious.
They already did. Her actions in
Destiny, while understandable, weren't always particularly wonderful, and her actions in
Zero Sum Game have certainly prompted a lot of controversy. And that's ignoring the fact that she was never a perfect President in the first place -- there are people who legitimately criticize some very important decisions she made in
Articles of the Federation.
ETA:
For my money, I really enjoy Bacco and think we haven't seen enough of her. She has, after all, only appeared in eight books (
A Time for War, A Time for Peace;
Articles of the Federation;
Destiny I: Gods of Night;
Destiny II: Mere Mortals;
Destiny III: Lost Souls;
TNG: Losing the Peace;
A Singular Destiny; and
Typhon Pact: Zero Sum Game). Realistically, given the sorts of events TrekLit often depicts, the Federation President ought to appear far more often.
