Senate Democrats felt encouraged Friday after Sen. Susan Collins (Maine) emerged as the first Senate Republican to publicly oppose the House-passed budget blueprint, named after Budget Committee Chairman Paul Ryan (R-Wis.).

“I don’t happen to support Congressman Ryan’s plan, but at least he had the courage to put forth a plan to significantly reduce the debt,” Collins said on WCSH 6, an NBC affiliate in Portland, Maine.

If Reid can show that a bloc of Senate Republicans will not support the dramatic spending cuts and sizable tax cuts passed by the lower chamber, it would help his negotiating leverage with Speaker John Boehner (R-Ohio).
