Republicans face growing concerns in North Carolina and Georgia Senate races

The concerns were highlighted in recent reports involving Republican campaign officials, senators and political operatives, who say both races are becoming more difficult for the party than previously expected.

Republicans currently hold 53 of the 100 seats in the US Senate, compared with 47 held by Democrats. Democrats would need to gain four seats, while retaining their existing seats, to secure a majority.

In North Carolina, Republican candidate Michael Whatley is running against former Democratic Governor Roy Cooper.

The Washington Post reported that some Republican officials have privately expressed concern about the race, while Republican campaign groups are reviewing how much additional money should be invested in the contest. A Republican political action committee recently cancelled about six-point-five million dollars in advertising reservations in the state.

In Georgia, Republican efforts are focused on challenging Democratic Senator Jon Ossoff. Recent election analysis has placed the race in a more difficult position for Republicans than earlier in the campaign.

The Cook Political Report said on September 23 that the overall Senate contest remained highly competitive, with viable paths for both parties to retain or gain control of the chamber.

Republican officials, however, have continued to say they are not abandoning either North Carolina or Georgia and are assessing where campaign resources can have the greatest impact.

The races come as Republicans defend their Senate majority in an election cycle shaped by economic concerns, the war with Iran and President Donald Trump's approval ratings.

With the November election approaching, both parties are expected to continue investing heavily in the key Senate contests, including North Carolina and Georgia, as the battle for control of the chamber enters its final weeks.
