Obamacare is the one consistently losing issue for Democrats and that is why so many of the endangered incumbents are running from President Obama. None of those in jeopardy are asking him to campaign for them and they didn't even take part in the global warming overnight "talkathon" this week with other Democrats in the Senate.
Democrats are desperate to find another issue to focus attention away from the utter failure of Obamacare implementation. Obama is talking about minimum wage instead of his jobless economic recovery. 2014 looks to be a good year for Republicans. I think the Republicans will keep control of the House and very well may take the Senate, if the right candidates are run and no idiotic remarks are made on the campaign trail!
