I've considered this "risk" and I'm willing to take it. What exactly are you worried an extra conservative justice will do? Republicans have had multiple chances to shift the pro-life/pro-choice balance but they never have the balls and I doubt they grow them. With corporate stuff, Hillary appointments would be just as bad the Republicans.
Really?Next session, the supreme court is going to take up more abortion related cases, on whether the law in Texas are constitutional or not.
That could just be the beginning. Of course, that's really only one issue. The Obamacare rulings show just how important the supreme court can be, years of fighting for universal healthcare could have all been for nothing. There was also that case where the Supreme court invalidated parts of the Voting Rights Act. I'm not going to bother listing every possible case, but there are plenty of important issues that could reach the Supreme Court, environmental regulations, gun control, the death penalty.
By the way, both of the justices appointed by Bill Clinton opposed the citizen's united ruling.
But frankly, the supreme court is only the tip of the iceberg.
The EPA has greatly expanded regulations during the Obama administration, a Republican would roll those back. Obama's immigration executive order could be rolled back, depending on which Republican is in office.
We would likely go back to a neo-conservative foreign policy. (and no, Clinton is not even close to most Republicans on foreign policy.)
Perhaps the most terrifying (for me), is the possibility that Republicans could eliminate the filibuster, giving them complete free reign over all 3 branches of government. Can you imagine the havoc they could wreak? Obamacare would be repealed and banking regulations would be gutted, and that would be the beginning. It would be every liberal's worst nightmare.
Even if the filibuster isn't repealed Republicans could get 60 seats in the Senate in 2018 if the Democrats don't make gains in 2016 (which we won't if Sanders is the nominee).
