What is the biggest hurdle in getting a medical marijuana bill passed?

The Senate in many ways is a much more difficult chamber to operate in than is the House. The House is the peoples' house, the peoples' chamber. 435 members of Congress in the House—obviously it's supposed to be the popular chamber, the populist chamber. The senate is supposed to be the upper body, the staid upper body which has great figures like Senator Bird in it who are historians; they know the history of the Senate deeply, they know the history of the country. They're supposed to be the conscience of the country. And in many ways, the senate is a much more contemplative body than the House is, taking nothing away from the House, but the senate in many ways is much more contemplative than the House. They view themselves a little bit more that way. And therefore, there's this great sense of responsibility among senators to the country, to their constituents, and therefore it can sometimes be difficult to get anything done in the Senate, actually.
