The Senate is expected to resume debate Wednesday on campaign finance legislation aimed at undoing a controversial Supreme Court decision that eliminated limits on corporate spending.

Jim Manley, spokesman for Majority Leader Harry Reid (D-Nev.), announced the decision to take up the Disclose Act in a Twitter post Tuesday.

Although Reid is expected to schedule a cloture vote on formally taking up the bill Thursday, it is unlikely to pass, because Republicans have remained united in their opposition to the legislation.

With virtually no chance of meaningful legislation being enacted before the election, Reid has sought to use the floor as a campaign forum by scheduling votes on issues supported by the Democratic base, such as immigration legislation, repeal of the military’s “don’t ask, don’t tell” ban on openly gay service members and campaign finance.
