Better, but not remotely enough for what he expected of NASA. Constellation was a nice framework, but it was too many spinning plates for a program that was too ambitious, not focused enough, under-budgeted and over-promised. Then you got Obama, who decided to take NASA back to square one for deficit hawk good boy points and unleash a pork tornado on the damn agency that was an even bigger clusterfuck than Constellation ever would have been for less return on investment. Don't forget, the nickname for it was "Senate Launch System" for a reason.
But really, what it boils down to is whose name goes on a plaque that ends up in some godforsaken corner of the planet as "the President who picked up where Kennedy left off" or somesuch bullshit, as if the whole-ass reason we put people on the Moon to begin with wasn't to make the world's most expensive point about how accurate our nukes are. And the US's lingering reluctance to just admit we're not building better than the Saturn V, and the smart, cheap play is just to reverse engineer that big bastard, take it back to the drawing board for a modernization pass, and build new, cheaper, better Saturn rockets.
