Obama-Romney Battle Plans Set for Final Charge WASHINGTON - Two months before the election, President Obama and Mitt Romney agree on one thing: the collection of states where the race will be decided. Jim Wilson/The New York Times, left; Doug Mills/ The New York Times Mitt Romney outside campaign headquarters in Boston on Saturday before heading to Virginia. President Obama was in Florida. As Mr. Obama opened a two-day bus tour of Florida on Saturday, Mr. Romney set his sights on trying to put Virginia back in the Republican column. Television advertisements from both sides were filling the airwaves in those two vital states and six others from Nevada to New Hampshire, while outside groups supporting the candidates tested for traction elsewhere. With the political conventions over, the battle to determine whether Mr. Obama will win re-election or Mr. Romney will become the 45th president of the United States is fully engaged. The race has been deadlocked, according to many measures, and each side was predicting that it would see no lift from its convention. That seems to have been true in Mr. Romney's case, while Mr. Obama's aides were hopeful that new polls due out this week would prove them wrong. But for now, Mr. Obama may hold a slight edge because the race remains essentially tied, which means voter disappointment has not turned into a resounding call for his defeat despite the challenging economic climate. "Now, our friends at the other convention were more than happy to talk about what was wrong with America but not talking about what they'd do to make it right," he told supporters on Saturday in Seminole, Fla., only a few miles from the site of the Republican convention. Mr. Romney, speaking to veterans in Virginia Beach on Saturday, referred to the disappointing jobs report released a day earlier. "This week has not been a lot of good news," he said. But I'm here to tell you things are about to get a lot better. Presidential races take place on many levels, some easily visible, others more shrouded. As the clock runs down, both sides make tough decisions about which states to compete in and which to abandon. Advertising themes get tested and changed as strategists hunt frantically for the right appeals, and get-out-the-vote teams target wavering voters with tailored messages. Behind closed doors, the candidates are preparing for the most crucial remaining events, the debates. And in courtrooms, lawyers are battling over who is on the ballot and who can vote. Unforeseen events, economic or otherwise, could also still have a significant impact on the outcome of the race, much as the financial crisis did four years ago this fall. Here are a few things to watch in the 58 days ahead: Electoral Map The roster of battleground states has not changed much, but one that Republicans had dearly hoped to put in play appears to have broken decisively: Pennsylvania. Mr. Romney spent time and money in the state, which voted Democratic in the last five presidential elections, but Republican strategists now say it seems out of reach. Wisconsin, which has 10 electoral votes and is home to Mr. Romney's running mate, Representative Paul D. Ryan, may offer Mr. Romney the best chance to expand his options. Republicans have not won there since 1984, despite fighting hard in almost every election. Wisconsin was not one of the eight states where the Romney campaign placed its first flight of general election ads late last week, but one party strategist said, "Keep watching." By this point, Mr. Romney had hoped to put at least a few more states into safer Republican territory. North Carolina, which Mr. Obama narrowly carried in 2008, is at the top of the list. But the state is still competitive enough that Mr. Romney and Republican groups feel compelled to keep advertising there, complicating their hopes of making Wisconsin and Michigan more competitive. Some Democratic strategists say that winning Florida remains a reach for Mr. Obama, but his visit this weekend suggests that the White House has not given up and at a minimum will make Mr. Romney spend a lot more time and money in the state.
