Obama's Budget: But How Do the GOP Three Feel?

... that they won't reveal it until the full Obama budget comes out in April. From Specter's statement:

It is impossible to evaluate adequately the President's ten-year budget until the release of the full documents.

Here's how Collins put it:

I will closely examine the full budget proposal when the details become available in the coming weeks.

Snowe was less direct in her response to the budget, remarking that the budget outline was "bold with its intention" but "scarce on details." Still, don't look for these three to get out too far in front of the budget this month -- despite Snowe and Specter's admirable climate change advocacy. They're likely to be watching how centrist Democratic critics air their grievances before making their opinions known.

But keep in mind that the budget will be immune to a filibuster, meaning that Democrats can afford to lose eight of their own members (assuming the Minnesota race remains unresolved) without the need to gain a GOP vote.
