Appointing more Supreme Court Justices? [View All]

Personally the fact that the Supreme Court has so many conservatives in it unsettles me. Especially since probably within the next 20 years were going to have a federal marriage equality case that will no doubt lead straight to the top and I believe some of our own liberal justices up there may not even back us on it. I know that we have had up to 13 Supreme Court Justices on the bench at one time. The President appoints Justices, confirmed by the Senate, when one passes away. But the legislature itself can, without the President, appoint a justice of it's own. What are the guidelines for that? And do you think any side could do it in todays America without totally pissing off a massive portion of our country? Personally I'd love to get some moderates up there...

Your two cents?
