NBC News: “Joe Lieberman, a former U.S senator and the 2000 Democratic vice presidential candidate, endorsed Sen. Susan Collins, R-Maine, on Wednesday. Lieberman is also appearing in an ad for Collins as she faces perhaps the toughest race of her career. ‘I’m a lifelong Democrat but I put my country first, always. That’s why I’m supporting Susan Collins for Senate,’ Lieberman, a Democrat turned independent, said in the ad, which is paid for by the Republican Jewish Coalition.RJC is spending $400,000 to run the ad on digital platforms, aimed at persuading women voters in Maine, according to the group’s spokesman Neil Strauss. Lieberman called Collins ‘a fighter for women’s issues’ in the ad.”
“Lieberman’s relationship with Democrats turned frosty after his strong support for the Iraq war — and he was defeated in a 2006 primary for his Connecticut seat. He ran that year as an independent and won. In 2008, he endorsed Collins for re-election and backed Republican Sen. John McCain’s presidential bid. He left the Senate in 2013. Collins has easily won her past election challenges, but her brand has suffered at home due to her support of many of President Trump’s initiatives. She currently trails Democrat Sara Gideon, the speaker of Maine’s state house, by 4.5 points in the RealClearPolitics polling average.”
