It is Election Day.

PRESIDENT DONALD TRUMP: You got to go out and vote.

BARACK OBAMA: Don't boo. Vote.

Keeping control of the House would validate President Trump's governing style and mean full speed ahead for Hill Republicans to move his agenda. But if the GOP loses its majority it will need to to go on defense to protect Trump.

When the Democrats lost the House in 2010, they rapidly saw President Barack Obama's legislative agenda die.

Veteran Democratic strategist Paul Begala doesn't think it's hyperbolic to say that "everything" is at stake for Democrats heading into Tuesday's elections.

"They always say it's the most important election of your life," he says, explaining that in the past two years, Democrats learned the consequences of being "completely shut out" as the GOP controlled both Congress and the White House.

If Democrats fail to take back the House and make significant gains at the state level, they'll be shut out again, without a say in legislation and judicial appointments.

In one respect, this is a typical midterm election — a race shaped as a referendum on the president and the party in power.

But there are so many ways in which this election is anything but typical. We've seen a surge in first-time candidates, especially women and minorities. In the past several midterms, the party in power was relatively complacent compared with the party hoping to be in power. Heading into Election Day, Democrats have an enthusiasm edge, but Republicans have been getting steadily amped up, too.
