A new poll shows that Democrat Jon Ossoff has strengthened his lead in Georgia’s 6th Congressional District race, and the race tightening among Republicans.

A poll by the conservative website zpolitics and Clout Research shows Ossof leading with 41 percent of the support of those polled. But it also shows that former Secretary of State Karen Handel and fellow Republican Bob Gray are nearly tied, with Handel at 16.1 percent and Gray at 15.6 percent.

A poll from the same outlet last month showed Ossoff leading Handel with 32 percent, Handel at 25 percent, and Gray with 11 percent.

The new poll comes as the Republican candidates grapple with the House GOP’s proposed bill to replace the 2010 health care law. The survey included only eight of the 18 candidates in the race along with “not sure” and “someone else” categories.

The poll showed health care is the No. 2 issue among likely voters in the district behind taxes and the economy. It also showed a small majority was pessimistic about the outcome of what happens with the health care law.
