What we learned from heated US midterm Senate debates
Candidates running for the US Senate in next month's midterm elections have taken to the debate stage over the past few weeks - with some heated exchanges and stinging personal attacks.
As the 3 November election approaches and parties fight for control of Congress, some clear themes have emerged, particularly within some of the hotly-contested Senate races.
Republicans running for office are facing the same question they have been asked in elections since 2016: how aligned are they with President Donald Trump?
Conservatives who have bucked the president in the past have generally not fared well with voters.
The president has seen low approval ratings in recent months, with polls suggesting voters are largely concerned with the cost of living and high fuel prices.
While some Republican candidates have remained in lockstep with Trump, a Reuters analysis indicated, external that two-thirds of candidates in competitive US House and Senate races have broken with the president in some way this election cycle.
Susan Collins, a Maine Republican running for her sixth term in the Senate who has repeatedly broken with Trump, is again putting clear distance between herself and the president.
"I voted with President Biden 91% of the time," Collins said during a debate last week.
"The fact is, this year alone, this Congress alone, I voted against President Trump 137 times," she said.
Collins is fighting a tighter Senate race than she expected against Democrat Troy Jackson, the former president of the Maine Senate. A New York Times/Siena University poll from mid-September suggests Collins could be ahead in that race by 3%, while others indicate Jackson is in the lead.
