First off, Obama;s has publicly stated federal funds will not got the DEA to harass people in states where med pot has been approved. The issue is the DEA doesn't give a shit, and is continuing to go after despenaries and what not that, I hope, are scapegoating some part of the law.... it sucks, but its not NEARLY as bad as it was under Bush.
Obama = "Bush lite" on this issue (and most others)
As far as I'm concerned, this is my litmus test issue. I could care less about how it affects me personally, but more along the lines that it's an issue of personal liberty, "change" (lack thereof), and Obama's apparent trajectory to pander to what is politically expedient. It should be clear to him that use of this substance really only directly harms the individual using it & weighed on that scale is relatively benign compared to what's out there.
Remember, the Obama administration came out against cali prop 19 ... please spare us how "it's what he had to do". If he were truly about significant change -- especially low hanging fruit like this -- he'd take a stand. But you know what, as much as I hate to say this, Rush, Hannity, O'Riley, etc. were all right that Obama doesn't like to stake out explicit ground. He's always got a political escape hatch.
I realize things take time, but when I see us being asked to "be patient" while he "plays the game from the inside", I say screw that ... enough is enough.
Barring a complete wingnut running against him in 2012, I will almost certainly vote for a third party candidate (or moderate conservative) ... basically anyone who is the least like a politician as possible & has a decent perpective.
