Not at all. Those are old Democrats who are now basically Republicans. Without Clinton running against two candidates, LA hasn't been battleground ever really. I mean it was part of Carter's coalition, but since 1968 has been Republican and even in 1964.
Clinton won 52% in LA in 1996, so certainly nobody spoiled it for Dole, and even Gore was within single-digits here. Try again.
Clinton also won 52% in WV in 1996 and Gore was within single digits, yet no one would claim that state was going to be a battleground. Same holds for Louisiana, just not to the same degree.
Carter won Mississippi in 1976. Therefore Democrats should totally target it.
The 1996 Louisiana results seem quiet surprising. Louisiana was the only Southern state where Clinton surpassed Carter 76's margins (Florida is an exception because it went through huge demographic shifts). Even in Arkansas, Clinton could not surpass Carter 76's numbers during both of his run for presidency.
