After a successful innings in the business world, Meg Whitman and Carly Fiorina are set for a political career.

Meg Whitman, the former eBay chief executive won the Republican nomination for the post of California's governor.

The former eBay chief will face former governor and politician Jerry Brown, who is currently the state's attorney general. In one of the most expensive primary campaigns in California, Whitman spent more than $81 million.

Meanwhile, former chief executive officer of Hewlett-Packard, Carly Fiorina, defeated former US representative Tom Campbell and Chuck Devore, to win the Republican primary in California to face Democratic US Senator Barbara Boxer in November.

The race for the US Senate is also an expensive affair. Fiorina spent nearly $7 million for the primary campaign in May.

Fiorina and Whitman won the ticket highlighting their conservative positions on social issues like abortion and gay marriage.
