Republican challenged by Democrat Troy Jackson in critical Senate race says she opposes Iran war and Canada tariffs

Susan Collins, the Republican senator for Maine, pointedly distanced herself from Donald Trump in a televised debate with Democratic challenger Troy Jackson on Tuesday, as she sought to present an image of independence in a state that has voted against Trump three times.

Proclaiming herself as not the US president’s “favorite senator”, Collins made the highly unusual boast for a Republican that she had voted with Joe Biden, a Democrat, more than 90% of the time when he was president. She also emphasized her differences with her fellow Republicans, saying she voted against her own party more than any other senator.
