Looks like it really is down to the wire. The latest Gallup Poll is expected to show Mitt Romney leading President Obama 49 to 48 percent among likely nationally voters. It’s important to note that the poll’s margin of error is 1 point, meaning that the president and Mitt are virtually in a tie. It’s the first poll since Hurricane Sandy, and shows a sudden surge by Obama. The last poll in October showed Romney up 51 to 46.
