Palin said comments she made last week in which she praised small towns as "pro-America areas of this great nation" weren't intended to suggest that other parts of the country are less patriotic, The Washington Post reported.
"If that's the way it came across, I apologize," Palin said in a CNN interview.
"Pro-America" comments by two U.S. representatives, however, created a backlash and threaten their re-election bids, the Post reported.
In Minnesota, Democratic challenger Elwyn Tinklenberg said he raised $1 million after incumbent Rep. Michele Bachmann's comments on MSNBC's "Hardball" questioned the patriotism of Democratic standard-bearer Barack Obama and suggested the media investigate whether congressional members are "pro-America" or "anti-America."
The non-partisan Cook Political Report recategorized the race from "likely Republican" to "tossup" and a Republican who lost to Bachmann in the party's primary began a write-in campaign.
In North Carolina, Republican Rep. Robin Hayes, locked in a heated campaign, also drew fire after telling a crowd "liberals hate real Americans that work and accomplish and achieve and believe in God."
A spokesman for Democratic challenger Larry Kissell, said Hayes' remarks belie the Republican's comments about being a consensus-builder and indicate "his hypocrisy knows no bounds."
