If you're reading this article about Bush's threatened veto of the Housing Bill, and then you see this press release from Randy Kuhl, don't be confused. Kuhl is co-sponsoring a housing bill, but it isn't the housing bill that Bush wants to veto.
That latter bill's author, Barney Frank, believes that he'll get significant Republican support. My guess is that support won't include Rep. Kuhl, because co-sponsoring an alternative bill that has no chance of passage is usually an attempt at inoculation. Kuhl can say that he supported a better alternative, even if that alternative was introduced a short time ago and has no chance of passage.
Update: Kuhl voted against the bill in three key votes today (here, here and here).
