* Roll Call…

Freshman Rep. Rodney Davis, R-Ill., holds a large lead over his GOP primary opponent, former Miss America Erika Harold, according to a poll obtained exclusively by CQ Roll Call.

Davis leads Harold by a massive 48 points in the poll of likely GOP primary voters commissioned by his campaign and conducted by the GOP survey firm Public Opinion Strategies. Twenty percent of respondents in the poll said they were undecided.

The survey showed Davis with 63 percent and Harold with 15 percent.

The results underscore Harold has a monumental challenge ahead to defeat Davis in the primary — which is just over three months away on March 18. Ninety-three percent of respondents said they had heard of Davis, while 45 percent said they have heard of Harold.

The poll interviewed 400 likely Republican primary voters via live telephone surveys between Nov. 19 and Nov. 21. It had a margin of error of 4.9 percent.

Harold also has a severe cash disadvantage, reporting just $99,000 in cash on hand at the end of the last quarter. Davis reported $882,000 in the bank at the time.

* Those numbers are almost exactly the same as an October 10th We Ask America poll…

The poll of 859 Republicans, taken Oct. 10, showed that Davis was the choice of 63 percent of the likely Republican voters, to 16 percent for Harold. About 21 percent of those polled were undecided. The poll had a margin of error of plus or minus 3.34 percent.

A poll taken exactly four months earlier, on June 10, by the same Springfield polling firm, We Ask America, found that Republicans favored Davis, 53.55 percent to 16.38 percent.
