The Democratic Congressional Campaign Committee will go after these Republicans during the next cycle. Democrats believe these GOP Members or Representatives-elect are vulnerable because they won by less than 55 percent in November and because their districts supported President Barack Obama in 2008. Roll Call compiled this list of Republicans, who are among those the Democratic Congressional Campaign Committee will go after during the next cycle.
