Oh no. Not another debate among those guys who are running for the Republican presidential nomination. By at least one count, Wednesday night's Dustup in the Desert — sponsored by CNN and Arizona's Republican Party — is the 26th such face-off — if you count forums and head-to-head encounters.

The run-up to Wednesday's Republican presidential debate in Arizona has highlighted immigration issues including the so-called DREAM Act, which proposes paths to citizenship for some undocumented children of immigrants. Three of the top candidates have said they support only part of the proposal — an unpopular stance among the Latino voters the candidates are courting in the border state.

The U.S. Supreme Court hears arguments Wednesday in a case about lies, big and small, and when those lies can be a crime under the Constitution's guarantee of free speech. At issue is the constitutionality of a law making it a crime to lie about being the recipient of military medals.

At the center of the case is Xavier Alvarez, a man nobody disputes is a liar. He lied about being an ex-professional hockey player. He lied about being an engineer. He lied about rescuing the American ambassador during the Iranian hostage crisis. He even lied about being a retired Marine.
