Millions of Americans cast their votes on Tuesday night in the Presidential election after a long and bitter campaign. The polls, which started at 6.30 PM Indian time onTuesday evening, ended this morning. The counting of votes is underway.

According to latest trends available, Republican candidate Mitt Romney is leading over his rival President Barack Obama in electoral votes. Each candidate needs at least 270 of the available 538 electoral votes to win the election.

In addition to the Presidential contest, voters are electing all 435 members of the House of Representatives, the lower chamber of Congress, and 33 of the 100-member of the Senate.

Analysts say Republicans will continue to hold their majority in the House, while the President's Democratic Party could maintain its slim majority in the Senate.

About 34 millions Americans cast their ballots in early voting over the last month. Mr. Obama voted a few days ago in his home city of Chicago, Illinois. Mr. Romney, voted on Tuesday in Massachusetts, the northeastern state he once governed.
