Republicans feel more optimistic about capturing Senate control

Republicans are feeling new optimism about their chances of taking over the Senate as struggling GOP candidates in Pennsylvania, Arizona and Ohio have stabilized their races, giving themselves a chance to gain ground in the polls after a tough summer.

Celebrity Dr. Mehmet Oz is starting to close the gap in Pennsylvania as a barrage of attacks on Democratic candidate John Fetterman are starting to take their toll.

In Arizona and Ohio, the Trump-backed GOP nominees came under criticism from fellow Republicans for lackluster fundraising and falling behind their Democratic opponents in the polls.
