As vote race tightens, Trump defends focus on immigration

WASHINGTON - The midterm elections to be held on Tuesday are the first major electoral battle since US President Donald Trump clinched the White House. Now, after two years, Democrats are eager to get back in the ring and slug it out with the GOP.

But no one has a crystal ball to tell who will win, especially after pundits, polls and political soothsayers have been wrong before.

The wild card in this year's midterms is the House of Representatives, while Republicans are expected to keep control of the Senate.
