Let the prognosticating begin. National political analysts are beginning to key in on Louisiana's 7th Congressional District as one to watch in the upcoming fall elections. The district will be a key indicator of the headway Democrats have made in the South, recently evidenced by Congressional election wins in Louisiana and Mississippi in two Republican strongholds. Congressional Quarterly notes that Democrats are hoping to continue their win streak with Cravins, another conservative southern Democrat with solid name recognition. The D.C. magazine, which keeps tabs on all Congressional races, had marked Louisiana's 7th District as a safe Republican seat but, with the emergence of a formidable challenger, says it will now be re-evaluate that rating. Boustany is sure to remain the odds-on favorite. His spokesman, Rick Curtsinger tells The Hill that the incumbent Congressman expects to report $600,000 cash on hand for the campaign in his first finance report due next week.
