I just got back and its midnight and I'm not about to go through everything you said point for point. But first off,
. Even in your point about Obama being a Blue Dog you take things out of context. He wasn't a member of them while in Congress and is ideologically to the left of literally every Blue Dog Democrat in national office (having a 100% and then 95% liberal rating for his first two years in the Senate). This is what I mean about dishonesty or arguments that cannot even be mistaken for being in anyway circumspect.
Second, all you have is to say "the republican healthcare plan," that supposed Republican healthcare plan is still better than what we had before once it is fully put into action. This is all assuming that states don't fight exchanges. But what do I know, I'm only from New England where Massachusetts was like a template for this plan and where it was passed by a Democratic House. What do you know, Massachusetts has the slowest rate of growth in healthcare costs in the nation the last time I checked.
It's not a personal attack, and isn't meant to come off that way and it isn't because you're Canadian (though your comments about places like Hampton are telling), it is because you keep talking like a guy who took some political science courses and now thinks he understands American politics at a sophisticated level. My best friends in law school are Canadian, they stump me all the time, even in regards to American politics. Though they're libertarian.
The bottom line is this, making general statements without applying them with real world examples and implications makes your argument necessarily weak when we are talking in terms of political efficacy and wasted opportunity. But please stop making those type of arguments so I'm not in the unenviable position of supporting Democratic cowardice.
