It turns out that Senator Schumer has voted four times against raising the federal debt ceiling, the Washington Examiner's Mark Tapscott reports, also passing along a quote from Michael Steel, an aide to Speaker Boehner. Mr. Steel says, "Sen. Schumer's voting record is like a dagger aimed at the heart of his own credibility. It is clear that the American people will not tolerate a 'blank check' hike in the debt limit unless we deal with the real issue: out-of-control Washington spending. We're listening to the American people, but the Democrats who run Washington, led by Sen. Schumer, are not."
Mr. Tapscott doesn't mention it, but the "dagger..heart" metaphor is a favorite of Mr. Schumer's, as the New York Sun noted in a pair of 2005 editorials (here and here) that may have inspired Mr. Steel.
