(CNN) - Republican presidential nominee John McCain's schedule on Thursday calls for a swing through the battleground state of Florida.

Rallies and events are planned in Daytona Beach, Ormond Beach, Altamonte Springs, Orlando, Plant City and Sarasota.

The most recent CNN Poll of Polls in Florida showed Obama with a three-point lead over McCain in Florida, 49 percent to 46 percent. The polls were conducted October 4 through October 15.

Democratic presidential candidate Barack Obama plans to meet voters in Indianapolis, Indiana. The state has voted for the Democratic candidate during presidential elections just once during the past 70 years.

Recent polls, however, show a tight race in Indiana. A CNN/Time/Opinion Research indicated McCain had a five-point advantage over Obama, 51 percent to 46 percent. The poll was conducted October 3 through October 6, and had a margin of error of plus or minus of 4 percentage points.

The Obama campaign has spent about $4.6 million in ad spending in Indiana during the past 30 days.

The Republican National Committee has picked up the slack for McCain in Indiana, but has been vastly outspent by the Obama campaign. The RNC has spent about $1.1 million during the same period.

Following the rally in Indianapolis, Obama is expected to leave the campaign trail and visit his ailing grandmother in Hawaii. He plans to return to the campaign on Saturday, Obama campaign spokesman Robert Gibbs said on Monday.

The other half the Democratic ticket, vice presidential nominee Joe Biden, will be in North Carolina, yet another traditionally Republican state that the Democrats are hoping to flip on Election Day.

He's scheduled to attend rallies at universities and colleges in Charlotte, Winston-Salem, and Raleigh.

A CNN/Time/Opinion Research poll released Wednesday showed Obama with a 4-point lead over McCain in North Carolina, 51 percent to 47 percent. The poll was conducted October 19 through October 21, and has a margin of error of plus or minus 4 percent.

The race was deadlocked at 49 percent in the same poll two weeks ago. That poll was conducted October 3 through October 6, and had a margin of error of plus or minus 4 percent.

Alaska Gov. Sarah Palin, the Republican vice presidential nominee, is expected to hold a rally in Troy, Ohio. She spoke to voters at three events Tuesday, with McCain joining her at two of them.

A CNN/Time/Opinion Research Corporation poll released Tuesday showed Obama with a 4-point lead in Ohio. The poll was conducted October 19 through October 21 and had a margin of error of plus or minus 3.5 percentage points.

Palin is then scheduled to travel to Beaver, Pennsylvania for a rally. The McCain campaign is increasingly focusing on the state, which carries 21 electoral votes. McCain held rallies in the state on Tuesday and visited the state twice last week.
