COLUMBUS, Ohio — It's still all about Ohio.
After a strong debate performance, Republican challenger Mitt Romney is intensifying his efforts in the state that's critical to his White House hopes, while President Barack Obama works to hang on to the polling edge he's had here for weeks.
Both candidates campaigned hard in the state Tuesday, the last day of voter registration ahead of Election Day, now just four weeks away.
"Find at least one person who voted for Barack Obama last time and convince them to come join our team," Romney told voters in Van Meter, Iowa, before hurrying eastward to make a similar pitch in Ohio, where he was campaigning with New Jersey Gov. Chris Christie.
Obama, in Columbus, called out, "All right, Buckeyes, we need you." His campaign had buses nearby, ready to ferry students or other supporters to registration centers.
As Obama wooed Ohio State University students here and Romney focused on the Democratic bastion of Cuyahoga County to the north, there were signs the president's Ohio advantage was narrowing. A new CNN poll showed Obama leading Romney 51 percent to 47 percent among likely Ohio voters. And Republican strategists familiar with Romney's internal polling contended the race was even closer — within a single percentage point — as the candidate enjoyed a post-debate surge of support.
"I promise you he's back in the game in Ohio," said Charlie Black, an informal Romney campaign adviser.
Like other Republicans, he credits Romney's strong debate appearance last week as the reason for an uptick in national polling. And Romney advisers maintain they're seeing evidence of that in the battleground states most likely to decide the election, Ohio among them.
"There isn't any question that he has breathed new life and new energy into the Republican Party," Ohio Gov. John Kaisch said Tuesday on a conference call with reporters. "We're seeing that there is greater intensity among Republicans and a great willingness to get out and vote and participate than we're seeing with Democrats."
With a hefty 18 electoral votes, Ohio is such a key state for Romney that one top adviser has dubbed it "the ball game" as the Republican looks to string together enough state victories to amass the 270 Electoral College votes needed to take the White House. No Republican has won the presidency without this Midwestern state, and if Romney were to lose here, he would have to carry every other battleground state except tiny New Hampshire.
Romney has far fewer state-by-state paths to the White House than Obama, who still has several routes to victory should he lose here.
Given the stakes and with just 28 days left in the campaign, Romney's schedule highlights his increased focus on the state: He's spending four of the next five days in Ohio, ahead of the second presidential debate in New York next Tuesday. Running mate Paul Ryan squares off against Vice President Joe Biden on Thursday for the sole debate featuring the No. 2's on the tickets.
Obama was being greeted in Columbus — for a rally at Ohio State University — by enormous letters that spelled out "vote early," a plea to the young voters who buoyed the president's bid in 2008. He arrived from the West Coast, where he had been raising millions of dollars for the campaign.
Obama campaign spokeswoman Jen Psaki dismissed the impact of polls showing a tighter race, saying Democrats always expected the race here and elsewhere to tighten ahead of Election Day.
"We have blinders on," she told reporters traveling on Air Force One. "We're implementing our own game plan."
Illustrating the competitive nature of Ohio, no presidential battleground has been more saturated with television advertising.
