Rahall remains a top Republican target in 2014, but he's hung on through a number of tough races, and some observers believe Republicans had their best shot at ousting him with President Obama at the top of the ticket last year.

The Charleston Daily Mail reported that Jenkins and Rahall have contributed campaign donations to each other.

According to WVMetroNews, Jenkins has served as a Democratic state senator since 2002, and in the state House for three terms prior to that.

Jenkins had served in various leadership positions in the state legislature, and the Democratic senate president stripped him of those positions after learning he would be switching parties.
