Obama was fairly subdued and rambling at times. I don't know of many Democrats particularly pleased by his performance.
But yeah, I don't like Romney anymore despite Obama's performance. His tax plan is still bullshit. A whimsical and apparently unnecessary 20% cut to everyone while still maintaining revenue neutrality. At the moment he can't even claim to be simplifying the tax code, because the only definite he offered simply caps deductions (at an apparently arbitrary amount, given he just threw out a bunch of possible numbers, math being one of those not terribly important aspects of tax plans, I guess.) The lack of specifics that actually cover deductions has been a problem throughout his campaign, and remains to be seen if he can even maintain that neutrality without raising middle class taxes. "Trust me" seems an awful lot when he's so incredibly focused on huge tax breaks for the rich as the crown of his entire policy.
He loved what he did in Massachusetts with Romneycare, praised his non-partisanship in getting it enacted. Hates Obamacare, will apparently repeal it on day one in an equal display of non-partisanship (getting elected into office will cow or convert Democrats, I guess?) Still keeps several important aspects of it somehow, except those pesky parts that pay for it.
A recurring theme is he can't offer anything definite, or... something bad will happen. The only successful way to become president is to offer a bunch of vague and idealistic goals, then come into office and make them all happen without any definite methods of making them actually happen. For me, it's not enough you run entirely on not being Obama, and then explain that through mere presence, your own four years will be fucking amazing.
So yeah, Obama was underwhelming by far. But Romney shifting tack a few weeks from the elections will still being incredibly vague on what his policies would actually entail beyond merely what they hope to accomplish means little. And I think Obama has more to gain in the last two debates than Romney does now.
