Polls: Many GOP Primary Voters Still Unsure

Two new polls of Republicans and those who lean Republican show a sizable number of likely voters remain undecided on the 2012 presidential race.

In a Gallup survey conducted last week, the percentage of undecided respondents doubled to 20 percent, up from 10 percent in a September poll taken two weeks ago. Since Gallup began polling the GOP presidential candidates in May, the percentage of undecided voters has decreased each month, but undecided voters in October are higher than they were in July (18 percent), August (17 percent), and September (10 percent).
