On Nightly News tonight, we will tee up this week's primary contests in Texas, Ohio, Rhode Island, and Vermont, which collectively offer 370 democratic delegates. We'll also be reporting the new MSNBC-McClatchy poll numbers that show Ohio and Texas to be very tight races. NBC's Lee Cowan is telling us the Obama campaign has been spending heavily on TV ads, hoping to deliver a knockout punch to Clinton on Tuesday. Yet, mindful of the polls, they are trying to guard against seeming over confident. Ron Allen is in Ohio covering Hillary Clinton. Her campaign is under no illusions as to what losses on Tuesday will mean to the future of her candidacy. In his report tonight, Ron will include a little of Clinton's cameo on last night's Saturday Night Live, where she engaged in some self-deprecating humor. Tom Brokaw will also be a part of our campaign coverage, as he looks at how Texas now finds itself in the rare position of having real political influence during a primary season.
The heavy snow seen in many parts of the country has resulted in a dangerous avalanche season. NBC's Peter Alexander has a terrific piece tonight on what may be your best chance for a successful rescue if you ever find yourself buried in snow.
We have full coverage of today's Russian presidential election, and why in a spite of a virtual landslide for Dmitry Medvedev, Vladamir Putin will likely remain very much in the picture.
Veteran correspondent Tom Aspell is in Gaza, where more than 100 Palestinians have now died following Israel's overwhelming show of force in the face of Hamas rocket attacks.
We will also have Richard Engel's reporting from Iraq on the historic visit today of Iran's president, Mahmoud Ahmadinejad, to Baghdad.
I hope you will join us for the Sunday edition of NBC Nightly News.
