After winning election by the narrowest of margins in 2008, Sen. Al Franken looked like one of the GOP’s most inviting Senate targets in 2014.  But instead, the party is facing the reality that Franken is proving to be a much more resilient opponent than expected, and his uncontroversial first term is raising doubts about whether Republicans can even recruit a first-tier candidate against the former Saturday Night Live funnyman.

The list of potential, formidable candidates is short.  Coleman, in an interview with National Journal, categorically said he wasn’t going to run for the Senate in 2014, denying the GOP one of its best-known possible challengers.
