WASHINGTON - Millions of Americans are heading to the polls this Election Day, as candidates seek to bring the battle for the balance of power in Washington to an end.
All 435 House seats are at stake, as well as 37 seats in the Senate. And a record 37 states will elect governors.
There are also several important ballot initiatives up for vote, from banning Islamic Sharia law to legalizing marijuana.
Some of the first election results are coming from Indiana, where polls close at 7 p.m.
"People are engaged. That's democracy in action. I think that's very healthy," said Republican Senate candidate Dan Coats.
"People will decide today," said Democratic opponent Brad Ellsworth. "A lady just walked out of here and said, 'We sure hope you win.' And that's the encouragement you need."
House Minority Leader John Boehner has already cast his vote. He could be House Speaker if various analysts turn out to be correct, and Republicans win somewhere between 50 to 90 House seats. They only need 39 seats to wrench control from the Democrats.
Polls begin closing in some states at at 7 p.m. ET, and will continue until 1 a.m. ET, when polls close in Hawaii and Alaska. Stay with CBN News Election 2010 for continuous coverage, with special LIVE updates at 9 p.m. & 11 p.m. ET.

It's a tougher battle for Republicans to win the Senate.
They need 10 seats and most predictions are the GOP will pick up seven to nine. Yet, Republican numbers seemed to be surging in last-minute polls.
One of the likely Republican victories will be in Florida, where Tea Party favorite Marco Rubio has been fighting Republican-turned-Independent Charlie Crist for the Senate seat.
"God willing, tonight I will have the opportunity to serve in the United States Senate," Rubio said.
"I'm the only one who can beat Marco and I hope that people don't waste their vote today," Crist said. "Get out. They cast their ballot for common sense."
Monday night, the political heavyweights were out, stirring Americans up to get out and vote.
"We need you to get fired up," First Lady Michelle Obama said. "We don't have more time."
Dozens of governorships are also up for grabs -- an important matter for 2012, since governors play a big role in redistricting and shaping how states will vote in the future.
Political experts said this election is considered a referendum on both the Democratic-controlled Congress and President Barack Obama's first two years in office.
