Larsen: A killer Super Tuesday?  Perhaps for the GOP, but
Democrats must wait  Whatever else one can say about the long-
waged presidential primary contests, they have made for the most
interesting primary in recent years, most especially in the race
for the Democratic nomination.  At one point, the Democrats had
nine candidates vying for the nomination. Now, the field has
been whittled to three &#8212; front-runners Sens. Barack Obama
and Hillary Rodham Clinton, and former U.S. Sen. Mike Gravel.
An even more crowded field sought the Republican nomination.
Thirteen candidates entered the race. Now, only five remain
&#8212; front-runners Sen. John McCain and former Gov. Mitt
Romney, along with former Gov. Mike Huckabee, Rep. Ron Paul and
Alan Keyes.  Political junkies have been having a field day
following the twists and turns of the campaigns, as well as the
ups and downs of the candidates. But, more important, the
presidential primary campaign has invigorated the electorate.
