CHARLOTTE, N.C. (AP) - Heard enough from the presidential candidates? Here's an answer: Vote now and put the election behind you.
Early voting in the presidential race begins Thursday, and in the weeks to come millions of people in key states will cast ballots that could prove decisive on Election Day. They did in 2008, when President Barack Obama's margin of victory relied to a great degree on early votes cast in such crucial states as Florida, Colorado, North Carolina and Iowa.
These days, a call to vote early is a standard plea in Obama's campaign speeches.
"Because in Iowa, you don't have to wait till Nov. 6 to vote. You can be among the very first to vote in this election, starting Sept. 27," Obama told supporters Saturday in Urbandale, Iowa.
Republican challenger Mitt Romney is looking to build up that early vote as well, eager to erect a better firewall than John McCain did four years ago. But early voting has favored Democrats, drawing heavily from the African-American community, and this year Republican legislatures have tried to limit early voting in states such as Ohio and Florida.
If votes cast on Election Day decided the 2008 election, McCain would have won in Florida, Colorado, North Carolina and Iowa. But Obama won those states with an overwhelming early vote advantage, gained by mobilizing not only committed voters but also non-habitual voters with Internet ads, email and text messages and person-to-person home visits and phone calls.
This time, putting votes in the bank is even more crucial for Obama. Amid a fragile economic recovery and a persistently weak job market, every voter who decides early is a voter who can't change his mind later, if unemployment worsens.
The Romney camp is counting on four years taking their toll on Obama's supporters, lowering their intensity and making them a harder sell. Indeed, Obama's camp in 2008 closely monitored early voting patterns to determine whether they were in fact expanding the look of the electorate. The early voting patterns this time will show not so much whether Obama is changing the electorate and more whether he is actually mobilizing it.
"The key for Obama is getting the best votes out of their lowest propensity voter," Romney political director Rich Beeson said. "With an intensity gap, that's the first problem they are going to have."
Early voting begins in North Carolina on Thursday, just as the Democratic National Convention ends. Indiana and Kentucky are next on Sept. 17, followed by Wisconsin on Sept. 20. Contested states such as Michigan, New Hampshire and Virginia are among a dozen states that open the ballot boxes the following week, on Sept. 22.
In all, 32 states and the District of Columbia allow voters to cast early ballots, by mail or in person, without having to give a reason. Early voting has been expanding every four years, setting records in 2008, when more than three out of 10 votes were cast before Election Day. More than half of the ballots in Colorado, Nevada, North Carolina and Florida were cast before Election Day, with Colorado leading the pack with 78 percent of total votes cast early.
Across the country, Republicans have worked to curtail early voting over the past four years, and their effort is ongoing. Florida and Ohio officials are embroiled in lawsuits over early voting.
Republicans in Florida approved a law last year shaving the number of early voting days from as many as 14 to eight. Early-voting advocates are challenging that, and a panel of three federal judges recently determined the changes could hurt participation by blacks, who lean heavily toward the Democrats.
In Ohio, another election battleground, the Obama campaign sued over a Republican-backed state law cutting off early voting for most people on the weekend and Monday before Election Day. A federal judge on Friday agreed to restore the voting days, although Ohio's Republican attorney general, Mike DeWine, plans to appeal the ruling. Early voting in both states begins Oct. 2.
Weekend voting has been an effective tool for Democrats. Black churches in 2008 promoted "take your souls to the polls" programs, helping deliver churchgoers from Sunday services to polling places.
But whether this election can match or exceed the 2008 early vote is an open question.
"We're not dealing with a candidate who's running for the first time; we're not dealing with the establishment of an historic change, and we have an economic downturn," observed Kareem Crayton, a political scientist at the University of North Carolina who specializes in voting rights.
Paul Gronke, director of the Early Voting Information Center at Reed College in Portland, Ore., said that without the level of enthusiasm and excitement that existed in 2008 the early voting
patterns might build up more slowly. He also noted, however, that Romney, unlike McCain, has embraced some of the same social media techniques that Obama used in 2008 to motivate his early voters.
"For that alone, Obama has a bigger challenge," he said.
From Anchorage to Miami, state-specific mailers are ready to go to each candidate's supporters, informing them when voting offices are open or how to request early ballots. Volunteers are ready to call supporters - culled from email lists, voter files and even magazine subscriptions - to remind them to get their votes counted.
Ohio is "going to be close, but we have 35 days to have our supporters vote early," said Aaron Pickrell, Obama's senior adviser in the state.
Obama has been asking crowds to visit a website run by his campaign, gottavote.com, to get early-voting information.
All of this means that today's presidential campaign looks much different from those of old, when massive get-out-the-vote operations were confined mostly to the final weekend and Monday before the election. Now, voter turnout is becoming a two-month slog. That is why the airwaves are already clogged with television ads, mailboxes are cluttered with political mailings and people are picking sides even before the first presidential debates take place.
"The old adage in Republican politics was a 72-hour campaign," said Scott Jennings, Romney's top aide in Ohio. "But really, that's a misnomer these days. We are going to be treating every day like Election Day, especially when the early voting starts."
