SCOTUSBlog reports:

The Supreme Court on Friday added five new cases to its decision docket for the current Term, including a test of the constitutionality of a federal campaign finance ban as applied to a critical movie about Sen. Hillary Clinton when she was running for president (Citizens United v. Federal Election Commission, 08-205). The Court also agreed to decide whether the Constitution requires an elected state judge to step aside from deciding a case involving the financial interests of a major campaign donor (Caperton v. A.T. Massey Coal Co., 08-22).

The order list is here. You can find the relevant briefs here.
The grant in Capterton is especially interesting given that it was relisted a number of times. That is often a sign that someone is writing a a dissent from denial of certiorari.
There are still two more important election law cases on deck. NAMUDNO, which the court will almost certainly hear near the end of the term, and Deters, the Ohio petition circulator case, which I believe has a fair shot of being granted.
