Unlikely, since Bernie is doing better so far in the states with larger democrat and swing contingents. Southern states are more likely to go to a Republican candidate. The South has voted Republican quite consistently since 1980. There were a few defections in the '90s, and Florida in the last two elections; but the GOP still dominated the region. In fact, with the exception of 1976, the GOP has dominated the south since the late 1960s.
Overall, Bernie is doing better with the middle than Hillary is. The overwhelming majority of her big wins have been in the deeply conservative South, where she already has strong ties and recognition. Moving out of the South, Bernie is pulling ahead in overall wins, picking up 9 out of 12 states; with Clinton barely eeking out a win in two swing states, Iowa and Massachusetts, and doing only slightly better in a third, Nevada.
By contrast, Sanders' wins have been more decisive overall, with at 10 points difference or better; Michigan being the only closely contested race.
My predictions:
As the election moves into more traditionally liberal states, outside the Clinton stronghold, I am predicting more and stronger Sanders wins, particularly in the west, despite the lack of press coverage; and eventual defection of at least a large minority of superdelegates. Florida has been swinging Democrat in the last couple elections, so that is very likely up for grabs, and could go either way. Ohio is likely to also be a close race, but I'm leaning slightly to Bernie in that one. The strongly liberal Pacific coast states are probably going to go strongly to Sanders, with Clinton picking up the rest of the South; and possibly a few in the more conservative-leaning Atlantic coast states, as well as conservative Alaska.
Clinton appears to appeal predominantly to conservative-leaning swing voters outside the South, while Sanders is motivating those leaning more liberal, and picking up a substantial percentage of far-left third-party voters.
