Of course, this whole thing is about the Obama hatred... It's the root cause of the Tea Party's very existence.
If you ask a random republican what they don't like about Obamacare specifically, you'd most likely get a blank stare. They just oppose anything coming from him instinctively.
Obama made a huge mistake in 2009 when he failed to acknowledge that fact and instead wasted a full year trying to please everybody for the sake of "bipartisanship"
Like I said before, he's a punk who won't stand for anything except for throwing black people under the bus. The Republicans have been messing with him from day one and he's still trying to take the "bipartisan" route.
