I know that long, heartbreaking lists could be written about the crippled Democrats in Congress, especially in the brutally gerrymandered House (many from places like Texas and Missouri are maxing out to give funds to Ben Chandler's campaign).
But which Republican incumbents are seriously vulnerable? Any? I thought that if someone compiled a list, that would give kos readers a good chance to scope out those races and think about backing or getting support for any formidable Dem challengers.
