The Gallup poll for Monday was released in advance to Monday night’s third Presidential Debate between Romney and President Obama.

This most recent Gallup tracking poll before this one was conducted from Oct. 15 to Oct. 21, and showed Romney with a six percentage point advantage, 51 to 45 percent.

The next closest of the recent polls, Monmouth, has Romney leading by only three percentage points, 48 to 45 percent, and a recent IBD/TIPP tracking poll has Obama leading by six percentage points, 48 to 42 percent.

Also on Monday the latest Reuters/Ipsos Tracking Poll showed that Republican presidential candidate Mitt Romney had closed the gap on President Obama.

Obama had previously led in the Ipsos poll, but his lead has now vanished and the two White House contenders are tied, according to the latest results. The poll, which surveys likely voters online, found that both Romney and Obama are now tied on 46 percent of those "likely to vote." Previously Romney had been behind the president by 1 percentage point, according to the Ipsos poll published last Saturday. However, that tiny margin has now disappeared.

Ipsos pollster Julia Clark said, "Today's number emphasizes the fact that the race is very close. We enter the final debate with the candidates literally neck and neck," according to Reuters.

However, when the polls are broken down into the key swing states, Obama seems to have a slight edge still. The latest Reuters/Ipsos polls indicate that Obama would marginally take Florida, Ohio and Virginia. The Reuters/Ipsos poll was based upon data collected from 957 likely voters surveyed, and was conducted between Oct. 18 and Oct. 22.

When the poll looks at the larger pool of registered voters then Obama carries a three percentage point lead, taking 45 percent compared to Romney's 42 percent.
