Former House Speaker Newt Gingrich is expected to announce today his intention to form an exploratory committee for a 2012 presidential bid. Gingrich brings both experience and baggage to the 2012 field and is likely to run on his long record of fighting for a balanced budget. But his personal history—he has admitted to adultery and has been married a few times—might turn away religious voters in the primary as well as married women, a key voting bloc in the general elections, CBS reports. A Gallup poll of preferred Republican presidential nominees shows former Arkansas Gov. Mike Huckabee and former Massachusetts Gov. Mitt Romney leading the race with 18 percent support. Sarah Palin polled at 16 percent and Gingrich at 9 percent. Whoever emerges as the Republican nominee will have difficulty matching incumbent President Barack Obama's fundraising numbers.
