Washington (CNN) – The Republican presidential candidates face off Tuesday night just a few blocks from the place they all hope to call home: the White House.
The candidates share the stage at DAR Constitution Hall, just down the street from 1600 Pennsylvania Avenue. CNN is teaming up with leading Republican-leaning think tanks Heritage Foundation and American Enterprise Institute to host a debate that focuses heavily on national security and foreign policy issues, but which will also include top economic concerns, including the failure of the congressional super committee to find agreement to cut $1.2 trillion from the country's long-term debt.
The debate is the 11th major showdown between the Republican candidates and the first in 10 days.
It's also the first in which former House Speaker Newt Gingrich is firmly among the front-runners in national surveys, deadlocked with former Massachusetts Gov. Mitt Romney for the top spot in the nomination race.
According to a CNN/ORC International Poll released on the eve of the debate, 24% of Republican and GOP-leaning independent voters say they are most likely to support Gingrich for their party's nomination, with 20% saying they back Romney, who is making his second bid for the presidency.
Gingrich's four-point margin over Romney is within the survey's sampling error. A CNN poll released one week ago had Romney at 24% and Gingrich at 22%. Gingrich was at 8% in a CNN poll in October.
