I've got nothing against Democrats that will say something along the lines of:
"Yes, I don't like this. Yes, it does seem like politics as usual and he was being dishonest. However, its still early on and while this does make leery I would like at least a year to see what promises he keeps, what promsies he doesn't, and what steps he takes to fulfill his promises."
Its understandable. Its completely understandable not to want to judge the guy you voted for based on a single incident. No one expects the guy they voted for to be perfect and I understand the feeling of wanting to judge him over a reasonable course of time, like 1 or 2 years, before really making a judgement on rather he was completely lieing or being dishonest about his platform as a whole or if there was just certain issues where he had to compromise his principles due to the reality of situations.
The problem is, for most of the Democrats that are saying something akin to that they're adding in an attack at republicans daring to actually point out this issue. Whether it is them harping on him too early, or not giving him enough time, or other such excuses...none of those negate what he did and that it IS something to consider.
The amazing thing is this therad would've likely ended 3 pages ago if the majority of the democrats went "Yep, I don't really like his move on this. It goes against part of what he campaigned for. However, its only been 2 weeks, and I've liked more things than disliked that he's done so far, so I'm going to hold off on Judgement".
A few rabid republicans may still have gone "OMG! You didn't say you hate him and that he's a horrible human being, I'm going to bite your leg off now!" but for the most part it would've died out.
Instead we got responses that "he didn't keep his promise 100%" whatever that means, or that its okay that he broke the promise because these guys may be good so its not REALLY the kind of people he was talking about when he made the promise, and other such "rationalizations". The sad thing is, a lot of these rationalizations give credance to some of the attacks from the more rabid people on the right during the campaign about the Messiah-complex (really, could say the Reagan-Complex as republicans do the same thing with him) during the campaign.
