Clinton's campaign appears to have reached it's national zenith on about January 20th, the day after the Nevada caucuses, according to Gallup. At that time, Clinton led Obama 48%--28%. Since then, however, Obama has closed the gap almost every day. The gap has become so close, that Super Tuesday now has a wide-range of battleground states, as state level polling conducted since that time demonstrates: (all polls included here can be found at Pollster.com)

The Super Tuesday battleground has thus changed dramatically:
Safe Clinton (466 pledged delegates): Arkansas (35), Massachusetts (93), New York (232), Oklahoma (38) and Tennessee (68)
Lean Clinton (613 pledged delegates): California (370), Delaware (15), Missouri (72), New Jersey (107), New Mexico (26), and Utah (23)
Toss-ups (286 pledged delegates): Alabama (52), Alaska (13), Arizona (56), Connecticut (48), Kansas (32), Minnesota (72) and North Dakota (13)
Lean Obama (73 pledged delegates): Colorado (55) and Idaho (18)
Safe Obama (240 pledged delegates): Illinois (153) and Georgia (87)
Needless to say, with half of the Super Tuesday states now either "toss-ups" or favorable to Obama, the odds of Obama being knocked on Super Tuesday have declined dramatically. With the direction things are going, it seems entirely probable that Obama will sweep the battleground states, pick up one or two "lean Clinton" states, and finish, at worst, 100 delegates behind Clinton on Super Tuesday. There is simply no way that Obama drops out at any point in February if that happens.
The Super Tuesday battleground has widened, and as many as 15 states are probably within single-digits at this point. If that does not give you a reason to get active this primary, I doubt anything will the rest of the way. Due to the wonders of light rail and small northeast states, from Philadelphia I'll probably try to check out the scene in either Delaware of New Jersey before the big day.
