Obama campaigns for Clinton, turns effort to US Senate race

President Barack Obama on Sunday campaigned in the battleground state of Nevada for Hillary Clinton, the Democratic candidate he wants to succeed him in the White House - but he spent most of his time talking about the state's Senate race.

Democrats badly want to get back control of the Republican-controlled Senate in the Nov. 8 election, and are sending Obama, Michelle Obama and Joe Biden to states where close races could tip the balance.

In Nevada, Obama reserved most of his firepower for mocking three-term Republican US Representative Joe Heck, who had supported his party's presidential candidate until earlier this month when Donald Trump's campaign went into crisis mode by the release of a video in which he lewdly bragged about groping and kissing women.
