Three Republican Senate candidates — Indiana's Mike Braun, North Dakota Rep. Kevin Cramer and Tennessee Rep. Marsha Blackburn — have slim leads in new Fox News polls, while two Democrats — Rep. Kyrsten Sinema (D-Ariz.) and Sen. Claire McCaskill (D-Mo.) — have small advantages in polls of their states.
Democratic Rep. Kyrsten Sinema held a slim lead over Republican Rep. Martha McSally, 47 percent to 44 percent, with 8 percent undecided. Sinema benefited from some crossover vote, with 12 percent of Republicans supporting the Democratic congresswoman.
More than half of voters, 52 percent, viewed Sinema favorably and just 35 percent viewed her unfavorably. Slightly under half, 47 percent, viewed McSally favorably and 43 percent viewed the Republican unfavorably.
