There’s no breakthrough for Mitt Romney or Barack Obama in the most recent opinion polls. All show statistical dead heats, although Romney does now have a couple of single-point leads. And all show Romney’s white share below the 60% achieved by the Congressional Republicans in 2010. (More white share comparisons here—scroll down).

Ominously, the Congressional Republicans white share is polling five points lower in this contest.

• Pew Poll (Nov. 4) had Romney trailing Obama 50-47.

Pew’s white poll respondents favored Romney by 15 points:

• Today’s CNN Poll (Nov. 5) shows a tie between Romney and Obama, 49-49.

Romney white share:  57%, 17 points ahead of Obama. Oddly, non-white numbers are shown as N/A –not enough response.

• Monmouth/ Survey USA / Braun (Nov. 5) shows Romney tied with Obama 48-48.

Monmouth shows Romney’s white share at a high (for him) 59%, for a twenty point lead over Obama.

• Gallup (Nov. 5) has Romney ahead of Obama, 49-48. This is the first Gallup poll since Hurricane Sandy, when Romney had a five-point lead.

Gallup has not published a racial breakdown since Oct. 16, when it showed Romney getting a record 61% white share. That translated into a four-point national lead over Obama.

• Rasmussen Reports (Nov. 5) has Romney back a point ahead Obama, 49-48.

Platinum Subscribers to Rasmussen can view the crosstabs, which show Romney and Obama both edging up another point among whites, so that Romney’s lead remains 18 points:

Further indication of Romney (possibly fatal) weakness among Northern whites: in the much-touted swing state of Ohio, Rasmussen shows him back down to a tie with Obama 48-48. Romney’s white share in the state: a mediocre 56%, for a mere fifteen-point lead over Obama.

It’s rubbing off: Rasmussen also shows Republicans and Democrats tied in a generic Congressional ballot, 46-46.

The Republican white share: 55%—down five points since the 2010 Election.
