Little electoral challenge from Unionist right?

Mark Devenport interviews Robert McCartney QC MLA about the upcoming election (Realplayer reqd about 7 minutes 30 seconds in). His responses give the strong impression that there will not be a major electoral challenge from the UKUP at the next election. The call to his banner appears to have been unsuccessful despite rumours of NIO polls giving anti-St Andrews candidates a chance in a number of East Ulster constituencies. Instead he pushes the anti-agreement mantle towards the ‘heavy-hitter’ sceptics within the DUP. If this lack of direct electoral challenge holds true then “sit at home” becomes the DUP’s problem.
