BEST BETS FOR TUESDAY, MAY 06, 2008

	INDIANA-NORTH CAROLINA PRIMARY COVERAGE MSNBC, 6 p.m. ET There are all sorts of places to check out live coverage of tonight’s Democratic primary results from Indiana and North Carolina. CNN has the best tech gimmick (the precinct-isolating touch screen), and HD Net has Dan Rather, still following his newsman’s instincts in a new, less ubiquitous media platform. But for now, my favorite place to go is MSNBC, because of the odd-couple pairing of enthusiastic Chris Matthews and sardonic Keith Olbermann. If these guys roomed together after work, there definitely would be a sitcom here.
	AMERICAN IDOL Fox, 8 p.m. ET It’s down to the Final Four, and tonight there are no excuses for choosing a bad song: the surviving contestants get to pull from a 500-song list of classic rock and pop songs. Brooke White would have done well this week – but she exited tearfully last week, after a performance of “I’m a Believer” that judge Simon Cowell was right to call a “nightmare.”
	TARZAN, THE APE MAN TCM, 8 p.m. ET This movie, the first in the series and the one to introduce swimmer Johnny Weissmuller as Tarzan and Maureen O’Sullivan as Jane, was made in 1932 – just at the point in cinema history to be a little naughty, and feature some aquatic Jane nudity.
	BEAUTY AND THE GEEK CW, 8 p.m. ET How low will this show go to plumb the depths of reality TV? Tonight, it actually goes plumbing – by demanding that the remaining beauties unclog some toilets and bathtubs. So far, this series has managed to be sweet rather than snarky – but tonight’s task may change that delicate balance.
	AMERICAN EXPERIENCE: GEORGE H.W. BUSH PBS, 9 p.m. ET (Check local listings) Part two of this four-hour biography airs tonight, and isn’t the first Frontline this season to recount the events leading to President Bush’s launching of the Gulf War – but this is the first Gulf War, and a different President Bush.
	LAW & ORDER: SPECIAL VICTIMS UNIT NBC, 10 p.m. ET Stephen Collins guest stars tonight, playing a man caught in a romantic triangle – with his own son being the other man.
