Maybe it is a smart "it takes one to know one" move, but Obama campaign chief Jim Messina's decision to help British conservative Prime Minister David Cameron win reelection has outraged liberals on both sides of the Atlantic.

"Political consulting isn't a profession known for its demanding ethical standards. But no matter how flexible your relationship to the truth or how sleazy your ads, there is one line you aren't supposed to cross — going to work for the other side. The Tories aren't the Texas Republican Party. But they are the other side. I hope the Democrats who consider hiring him in 2016 understand that," wrote Daily Beast special correspondent Michael Tomasky, who is also editor of Democracy: A Journal of Ideas.

"At the end of the day he'll have to look at himself in the mirror and justify his actions," liberal Labour shadow minister Dan Jarvis told the London Telegraph.

Conservative political commentator Nile Gardiner, a former aide to conservative Prime Minister Margaret Thatcher, even called the move by Cameron a "desperate gimmick" that casts a cloud over what the prime minister stands for.

The BBC first reported that Messina, wooed by Labor for help in the upcoming 2015 election, chose to help the conservatives in England. The news agency said that the Tories, facing a troubled economy, hope to copy President Obama's reelection formula concocted by Messina and which crushed Republican Mitt Romney.

Messina told BBC: "I have long admired Prime Minister Cameron. While I will not be moving to London, nor will I be managing any type of day to day political operations, I will be offering strategic campaign advice leading up to 2015."

Messina artfully used social media and a wealth of statistics to pinpoint supporters of the president and get them to vote.

But he is taking fire because liberals think he should stay on his team, in this case Labor, traditionally linked to the Democrats.
