Addivinola e-mailed a statement in the morning: “Even though the results of the yesterday’s primary are not what we hoped for, I came in second to Tom Tierney in a three-way race which would not be possible without motivated people who helped me.  While I am disappointed, I am definitely not discouraged and look forward to announcing my run against Markey in 2014 …  “While I respect the victor’s accomplishment in this race, most of us know that this candidate does not represent conservative ideas and advocates for higher taxes and Obamacare.  It is expected that he will not go after Markey’s record.  I wish him luck in his endeavors, but I am looking forward to re-entering the race for the next election and invite activists to become engaged in supporting me.”
