Washington (CNN) ? House Republicans may be deciding on a leader this week, but Republicans across the country still have no clear front-runner for the 2012 presidential nomination.

According to a new Gallup poll, 19 percent of rank-and-file Republicans would support Mitt Romney for the Republican nomination. Romney leads the pack of potential GOP nominees, but Sarah Palin is close behind with 16 percent and tied with Mike Huckabee who has the same amount of support. The three-point margin between the three potential nominees falls within this poll's sampling error, indicating that there is currently a three-way tie for GOP presidential favor.

Newt Gingrich is hot on their heels; 13 percent of Republicans say they'd support a Gingrich bid for the presidency. Since the last Gallup poll, released in September, both Gingrich and Huckabee have seen four-percentage-point increases in support.

A CNN/Opinion Research poll conducted days before the midterm election also found that Republicans lack a favored candidate to clinch the GOP nomination. Released November 4, the poll found that 21 percent of Republicans surveyed supported Huckabee, 20 percent were behind Romney, and Palin came in third, favored by 14 percent.

Candidate strength is largely determined by name recognition and past bids for the presidency fare well for Romney and Huckabee, as well as Palin, who ran for vice president in 2008. Though Gingrich is known for his efforts to lead the Republican takeover of Congress in 1994, he has a lower favorability rating than the top three, according to the CNN poll.

No one has officially announced a bid for the GOP presidential nomination, but watching candidate travel to Iowa, New Hampshire, and South Carolina, the first states to vote in a presidential primary, will aid in the guessing game. Rick Santorum, who currently has one percent support among Republicans according to Gallup, recently traveled to New Hampshire and Sarah Palin lists stops in Iowa and South Carolina as part of her upcoming book tour for "America by Heart: Reflections on Family, Faith, and Flag."

Gingrich is in Iowa Tuesday and Wednesday to promote his new book "Valley Forge," and plans to continue the book tour with a visit to South Carolina next month. Huckabee will travel to Iowa this weekend for a conference on family values. Tim Pawlenty visited the Hawkeye state while stumping for GOP midterm election candidates; he currently has four percent of support according to the Gallup poll. Four percent of Republican supporters also back Haley Barbour, who has traveled to Iowa and New Hampshire in recent months, while Romney hit all three states on his 25-state pre-election day tour.

The Gallup poll was conducted by telephone from November 13-14 and includes 925 interviews with Republicans. It has a sampling error of plus-or-minus 4 percentage points.
