And how does the House get such a bill past the Senate, and Obama to become federal law?
Colorado passed a marijuana referendum (so did Washington). This is a serious liberal issue, and the problem is even though it's legal now in Colorado for recreational use, the Feds can still come in and bust you. Republicans can use this to push a bipartisan state's rights bill (and we can use the same state's rights to nullify Obamacare at the state level). If the Democrats want to be the party of screwing liberals in Colorado and Washington right after the election, let them.
