Scott Applewhite, File) (Newser) – The congressional midterm elections are coming, meaning it's time to mine the tea leaves for potential losers. So, who might be facing the music come November? Of the Senate's 10 most vulnerable, nine are Democrats, according to Roll Call. A sampling from its list: Mary Landrieu—An oddball voting process and calendar, and a strong GOP contender, Rep. Bill Cassidy, could send the Louisiana Democrat home. Mitch McConnell—The majority leader is the list's lone Republican. He faces Democrat Alison Lundergan Grimes, who has proven herself a formidable fundraiser. President Obama's unpopularity in Kentucky isn't helping her. Jeanne Shaheen—The popular New Hampshire Democrat is facing a well-known face in Scott Brown, who should see a boost after his primary next week. Click for the full list of 10. Politico offers a similar analysis for the House: Michael Grimm—Indictments tend to put a damper on campaigns, and Grimm's isn't helping the New York Republican. However, polls still indicate he's tied or even ahead of his challenger. Steve Southerland—Former Sen. Bob Graham's daughter, Gwen Graham, is a formidable opponent for this Florida Republican. She's bringing dad on her campaigns and has raised lots of money. Rick Nolan—The 70-year-old Minnesota Democrat has struggled to raise money against a strong GOP opponent, Stewart Mills, called the "Brad Pitt" of the party. Click for the full list of five.
