I can’t figure out what they think the ultimatum is:

ABC News’ Z. Byron Wolf Reports: Democrats sent a clear message to the White House tonight – make some of the $700 financial industry bailout money available to the domestic auto industry or else. And they want an answer by Friday.
[…]
“Your decision to utilize the TARP funds, or to work with the Federal Reserve to make available assistance through its existing lending programs, or both, are essential to the Congress’ ability to address this critical economic situation in a timely manner, and would also eliminate the uncertainties inherent in the legislative process, ” say Senate Makority Leader Harry Reid, House Speaker Nancy Pelosi and Democratic committee chairmen in the letter.
They go on: “We are very hopeful that we can work cooperatively with the Administration and the Federal Reserve to provide urgent assistance and support our domestic auto industry, just as other nations are doing, during this extraordinarily difficult global economic collapse. We look forward to hearing from you on an expedited basis, since we will be notifying colleagues tomorrow of next week’s session

That’s the extent of the quote in the post. So what are they threatening? Do it or we’ll do it and we might fail? What kind of threat is that?
