Republican strategists claimed last night’s win in the 13th Congressional District of Florida was down to Ms Sink’s support for Obamacare, the President’s healthcare law, and said it would send “a loud warning for other Democrats running coast to coast”. The poll is also being seen as the opening salvo before November’s midterm elections, in which Barack Obama could lose the Senate. Having already lost the House to the Republicans it would leave the President a lame duck until he leaves office in 2016.
