Marco Rubio may soon get a boost from one of the Republican Party's key donors.
Billionaire casino magnate Sheldon Adelson is leaning toward supporting the Florida senator for the Republican presidential nomination, Politico reported Monday, citing sources. Adelson could endorse Rubio as early as the end of the month, the report said.
Adelson, the deep-pocketed Las Vegas Sands chairman and CEO, would provide a vital cash stream to Rubio's campaign. The 82-year-old funneled more than $90 million into conservative Super PACs in the 2012 election cycle, according to the Center for Responsive Politics.
