Washington (CNNMoney.com) - The Senate is set Wednesday to take a crucial test vote on Wall Street reform amid signs that proponents may have secured enough votes for passage.
Democrats will begin voting at 2 p.m. ET to end debate on the legislation, which aims to stop bailouts, shine a light on complex financial products and strengthen consumer protection.
Proponents need 60 votes to pass the test. Passage would be an important barometer since only 51 votes would be needed for Senate approval of the final bill.
"There comes a time when we have to put this thing to rest," said Senate Majority Leader Harry Reid, D-Nev., Wednesday morning. "We've been on this bill for a month."
Reid has said senators, including some Republicans, have told him they favor ending debate.
One key lawmaker, Sen. Susan Collins, R-Maine, said that she planned to join Democrats voting to end debate, calling the overall month-long debate "fair and open," in a statement.
