After last week's marathon live blog of Super Tuesday III, tonight's lone primary, West Virginia, should be called well before Wednesday begins (the most recent poll shows a 36-point Hillary Clinton lead). The networks will be covering the action, in very different ways. Polls close at 7:30pmET:

• ABC: Kate Snow follows the Clinton campaign and David Wright follows the Obama campaign.

• Bloomberg: Live coverage begins at 9pmET, with Ron Christie discussing results. World News with Charles Gibson will be updated for time zones across the country. Cynthia McFadden anchors Nightline.

• CNN: Wolf Blitzer anchors coverage starting at 7pmET, and Campbell Brown joins at 8pmET, along with the BPTOT. Anderson Cooper 360 airs at 10pmET, Larry King Live airs at MidnightET.

• FNC: Brit Hume anchors coverage of election results from 7-8pmET. Shepard Smith moderates the Strategy Room. Regarding the one hour of coverage, SVP Bill Shine tells TVNewser, "It's, so far, looking like it's going to be her night."

• MSNBC: Keith Olbermann and Chris Matthews anchor from 6-11pmET, and Dan Abrams takes over with After Hours from 11pmET-2amET. Mike Huckabee and Harold Ford, Jr. serve as MSNBC Insiders.
