Las Vegas casino tycoon Sheldon Adelson and his right-leaning advocacy group Freedom's Watch could be key in financing Republican campaigns across the country, according to a story in the Wall Street Journal.

As the paper wrote:

In the Las Vegas casinos that made Sheldon Adelson one of the country's richest men, a "whale" is someone willing to bet millions. Republicans are hoping Mr. Adelson will be their whale this election.

As PolitickerNV.com reported, Freedom's Watch targeted congressional candidate and state Sen. Dina Titus (D-Henderson) earlier this month with a series of robocalls highlighting her lack of action on Nevada's high gas prices. In June, the group aimed at Rep. Shelley Berkley with allegations that she doesn't back U.S. troops.

So far, the group's results have been mixed. According to the Journal, two of the three House special elections Freedom's Watch has targeted in heavily Republican districts have ended in failure, which could lead conservatives to question if Adelson's efforts are helping or hindering the party.
