Mitt Romney increased his lead in the Gallup daily tracking poll. He now leads 52% to 45%. I love the liberal mime that we knew this would happen. Polls always tighten as the election nears but now the polls seem to be widening. These results are for likely voters, who are the respondents Gallup deems most likely to vote based on their responses to a series of questions asking about current voting intentions, thought given to the election, and past voting behavior. Each seven-day rolling average is based on telephone interviews with approximately 2,700 likely voters; margin of error is ±2 percentage points.
