In the upcoming US mid -term elections, Hedge funds tycoon Tom Steyer will unleash a $100 million campaign spread in 7 states as an offensive against Republican party candidates, reports CNN. Backed by his environmental advocacy group the green billionaire is planning to go on an all out offensive to stop Republicans from controlling the Senate and key statehouses by November.

Steyer's advocacy group NextGen Climate calls Republicans as science deniers. It is positioned as a progressive counterbalance to wealthy oil and gas industry. It will also act as a foil to the pro-business groups and well-funded conservative donor networks.

Support for Democrats

The outfit of this San Francisco billionaire will heavily spend in the midterm to assist key nominees like Democratic Senate nominee Bruce Braley and Florida Governor Rick Scott.

Steyer's 2014 map includes Senate races in Michigan, New Hampshire and Colorado. Other key races will be Maine and Pennsylvania, which are home to Republican governors Paul LePage and Tom Corbett.

According to Chris Lehane, Democratic consultant who is advising Steyer, this is the year to demonstrate that climate can be used smartly to win political races.

Pro-climate Action

Lehane said the group will play an active role in races that feature a stark choice between pro-climate Democrats and anti-science Republicans. The Republicans are being dubbed anti science because they questioned climate change and were supportive of the interests of the oil and gas industry. Lehane also calls Republicans anti-immigrant and anti-women.

The advocacy group of Steyer notes that the climate issue will become a moral clash between right and wrong. It will boost the turnout among Democratic voting groups who are loathe to show up in midterm elections So the young voters, Hispanics and African-Americans can be encouraged to turn up for vote.

Meanwhile, indications are out that Republicans are not that weak. According to Business Week, the win by Industrialist David Perdue in the primary for Georgia's Republican U.S. Senate nomination speaks a lot.

Perdue won 51 percent of the vote to 49 percent for U.S. Representative Jack Kingston. The race was closely fought with the candidates exchanging leads.

Perdue is expected to unite Republicans in defeating Michelle Nunn, the Democratic nominee and daughter of former Senator Sam Nunn.
