Former Massachusetts governor Mitt Romney will announce next week about his plans for 2012 Republican presidential nomination in New Hampshire and the only negative point in him is his lack of private sector experience, a Romney aide told Reuters on Thursday.

The 64-year-old Romney is considered the early Republican front-runner who can challenge President Barack Obama in the November 2012 election. Romney tops many opinion polls, but he lags behind Obama. Romney planned to launch his campaign on June 2, at a mid-day barbecue in Stratham, according to the aide.

The president is a fine fellow but he doesn't have the experience in the private sector to know what it takes to get America creating jobs again, Romney told Reuters.

Romney has formed a presidential exploratory committee and has raised more than $10 million in just one day.

The healthcare plan that Romney developed for Massachusetts could be a key vulnerability for them.

A Gallup poll released on Thursday showed that former Alaska governor Sarah Palin at 15 percent close behind Romney who is at 17 percent.

Michele Bachmann, a U.S. congresswoman from Minnesota, is also considering entering the Republican presidential race.

Former Minnesota governor Tim Pawlenty and Newt Gingrich, the former speaker of the House of Representatives are the other Republican White House hopefuls, but many Republicans are not happy with the current nominations of presidential contenders.
