Is Lisa Murkowski vulnerable? Alaska's US Senate race

Now that Joe Miller has replaced Cean Stevens as the Libertarian nominee for the US Senate.  Will Joe get his revenge from 6 years ago.  I guess Lisa will need the majority of Democrats to save her.  Most conservative Republicans are going with Joe Miller.  We shall see when the debates happen.  There is also riff between Margaret Stock and Ray Metcalfe who is the better Democrat.  Ray Metcalf served with Lisa's father in the legislature in 1970's.  Go Joe Go.
