Tuesday marks six weeks until Election Day, but registered voters in two dozen states are already able to cast a ballot for president, with more states to allow early voting in the coming weeks.
In the 2000 presidential election, early voting accounted for 15 percent of the total ballots cast. By 2008, that doubled to 30 percent, according to the United States Elections Project at George Mason University. It's expected to be on the rise again this year.

The election is not over, we are told time and time again, and it's not. There are still some 40-plus days to go, there are still debates to be had. It's true that Mitt Romney trails President Obama in most key battleground states, but the margins are in single digits. And, lest we forget, it's not that presidential candidates down in the polls haven't come from behind to win in the past.
Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.
But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.
