Rep. Sandy Adams (R) has a long way to go to convince Florida voters to choose her over Rep. John Mica (R), a new poll showed.

Pitted against each other by redistricting, Adams and Mica are running in the same central Florida district. An internal poll released by Adams's campaign shows her favorability at 50 percent and Mica's at 72.

But 43 percent don't have an opinion about Adams, compared to 20 percent for Mica. That means Adams has a wider opportunity to make a first impression on new voters and quickly close the gap on Mica, argued a polling memo released Tuesday by Public Opinion Strategies.

The memo points out that in the areas of the district that Mica didn't represent already, Adams outperforms him.

And after voters were given bios of both candidates, Adams takes the lead in a ballot test, besting Mica by three points, within the margin of error. But while the memo says the bios for each candidate were neutral, Mica's emphasizes how long he has been in Congress, while Adams's emphasizes her Tea Party roots and freshman status in the House.

The poll of 300 likely primary voters was conducted Feb. 22-23 and had a margin of error of plus or minus 5.6 percentage points.
