A U.S. Senate vote on a Constitutional amendment to ban same-sex marriage is expected Wednesday. Senator Jim Talent, a supporter of the effort to change the Constitution, tells Senate colleagues the amendment is necessary to protect marriage from activist judges who would impose their will on people in all states. On a 4-3 vote the Massachusetts Supreme Court ruled a ban on same-sex marriage violated the rights of homosexuals and, in effect, approved of this kind of marriage. Talent warns that unless there is a federal ban courts like the one in Massachusetts could force their views on citizens of all states throughout the country. A two-thirds’ vote of the Senate is needed to move the process along. It’s believed the effort will lack the necessary votes.
