Frank Rich lays out why the "Clinton is inevitable" narrative is wrong. He makes a great case for why Barack Obama may not only beat her, but gives the GOP a much bigger fight:

The unspoken truth is that the Clinton machine is not being battle-tested at all by the Democratic primary process. When Mrs. Clinton accused John Edwards of “throwing mud” and “personally” attacking her in a sharp policy exchange in one debate, the press didn’t challenge the absurd hyperbole of her claim. In reality, neither Mr. Edwards nor any other Democratic competitor will ever hit her with the real, personal mud being stockpiled by the right. But if she’s getting a bye now, she will not from the Republican standard-bearer, whoever he may be. Clinton-bashing is the last shared article of faith (and last area of indisputable G.O.P. competence) that could yet unite the fractured and dispirited conservative electorate.
