Polls show a majority of voters now support gay marriage, and Democratic politicians in particular have raced to side themselves with public opinion.
President Obama announced his support for gay marriage last year, and earlier this month former Secretary of State Hillary ClintonHillary Rodham ClintonCongress steamrolls Obama's veto Trump: I saved former Miss Universe's job 'and look what I get out of it' Carson: Trump faces a debate 'learning curve' MORE said she supported gay marriage.
The Supreme Court has heard two cases on the issue this year. Many expect the court will strike down the federal Defense of Marriage Act, which prohibits same-sex couples from getting certain benefits offered to married couples.
It's unclear whether more Senate Democrats or Republicans will shift their positions in the coming days.
Manchin, Johnson and Pryor have expressed opposition to gay marriage, while Landrieu and Donnelly did not respond to requests for comment from Time, according to the publication's report. All five hail from states that Obama lost in the 2012 presidential election, though Obama did win Indiana in 2008.
Casey, Carper, Heitkamp and Nelson do not back same-sex marriage. All four have either opposed new legislation banning same-sex marriage or been clear proponents of civil unions and rights for same-sex couples.
