WASHINGTON (AP) — A Senate Democrat says House Speaker John Boehner's failure to get fellow Republicans to back his debt limit bill dramatizes the folly of a "go-it-alone" approach to the financial crisis.

Colorado's Michael Bennet tells CBS's "The Early Show" Boehner's decision to cancel a vote Thursday night on the GOP proposal leaves Senate Democrats and Republicans as the last hope to find a compromise bill. The nation's borrowing authority expires Tuesday in the absence of a law renewing the government's borrowing authority.

Bennet says he's "enormously disappointed" with political gridlock, asserting "there's a reason the poll ratings of Congress are in the basement."

He says he's against a temporary extension in the debt limit, arguing that would only allow Congress to postpone the kinds of tough decisions it must eventually make.
