(CNN) - Continuing his national surge, Herman Cain came in second place among Republican presidential candidates in a new national poll released Monday.
The Washington Post/Bloomberg survey of Republican-leaning voters showed former Massachusetts Gov. Mitt Romney on top with Cain, the former Godfather's Pizza CEO, in the No. 2 spot, slightly ahead of Texas Gov. Rick Perry.
Romney received 25% support, followed by Cain with 16%, Perry with 13%, Rep. Ron Paul of Texas with 6% and Rep. Michele Bachmann of Minnesota with 4%. The remaining candidates received lower figures.
The respondents who lean Republican said Romney, at 22%, would do the most to improve the economy. Cain, who has made the economy the central theme of his campaign, received 20% and Perry received 12%. Meanwhile, the questioners said Bachmann would do the most to hurt the economy. She garnered 14% followed by Paul at 11% and Perry at 9%.
The new poll was released one day before Tuesday's GOP debate in New Hampshire and shortly before Gallup released survey results that showed Cain trailing Romney by just two percentage points. The difference is within the poll's margin of error.
In the Gallup poll Romney received 20% support, followed by Cain at 18%. Perry saw 15% support in the survey with Paul behind him at 8%, Gingrich at 7%, Bachmann at 5%, Santorum at 3% and Huntsman at 2%.
But with 20% of Republicans and Republican-leaning independents still undecided, there's more work for GOP candidates when it comes to firming up support.
A Pew Research Center survey released Thursday showed Romney still on top with 22%, but Perry was next in line with 17%, followed by Cain with 13%, Paul with 12%, Gingrich with 8% and Bachmann with 6%.
The Washington Post/Bloomberg News poll questioned 1,000 adults between Oct. 6 and Oct. 9 with a sampling error of plus or minus 3.5 percentage points. The Gallup poll was conducted from among 1,064 Republicans and Republican-leaning independents by telephone from October 3-7. It has a sampling error of plus or minus 4 percentage points. The Pew poll questioned 876 Republican and Republican-leaning registered voters between Sept. 22 and Oct. 4 with a sampling error of plus or minus 4 percentage points.
