The measure will come to a vote on the floor of the Senate early next week. Reid’s move begins the endgame for the legislation even though he does not yet have the votes to overcome the anticipated filibuster from the bill’s opponents.

New York Senator Charles Schumer, who authored S. 3295, the Senate’s version of the DISCLOSE Act, has modified the bill to address concerns raised when H.R. 5175 was passed by the House earlier this summer. Democrats hope the changes will be enough to win the support of Maine GOP Senators Susan Collins and Olympia Snowe, both of whom expressed reservations regarding the House bill. For example, Senator Collins believes H.R. 5175 provides unions with special exemptions and a corresponding unfair political advantage over corporations.

It is unclear at this time whether or not changes to the Senate bill offered by Schumer will be enough to overcome Collins’ and Snowe’s objections. The Senate vote could come as early as Tuesday.
