On Pelosi, she has long been a religious person.
Some on the right have misguided ideas that makes this not make sense to them - they think only they are religious.
It's pretty hypocritical of them to attack her as anti-religion and then as too religious.
But the right might say it's hypocritical for liberals to say they have issues with the right-wing leaders and religion, while Pelosi says this.
There are differences. There is a huge part of the US that's the 'religious right', recruited into the Republican army - there is no huge 'religious left' army.
The types of pandering the Republicans do to win over this group raise concerns - including things like 'buying their support' handing them taxpayer dollars under the cover of paying them to do charity. The Republican Congress had an emergency passage for Terry Schiavo to pander, with Bush returning early to sign the bill in the middle of the night - the left doesn't have that.
Instead, I think that religion does appropriately influence the politics of both sides - 'care for the poor', 'love your neighbor' and so on are religious views affecting politics. Laws against murder, against theft, share religious values. There's a line drawn when you get into more purely religious things - laws that support one religion over another rather than just public issues, should 'respect your parents' be a law? Should there be a law against idolatry? The Muslims have countries who have gone a long way to crossing that line, do we want that?
Pelosi isn't using religion here for political purposes IMO, but expressing her views that religion influences her in more appropriate ways.
IMO, Republicans sometimes treat the religious right like a group to exploit - supported by reports in Bush's first head of the new 'faith-based' office that Republican officials would wheel and deal with the religious right, and then behind their backs call them 'nuts'. Indeed, George Bush's own history has him campaigning for his father, who lost - and the next time, Bush found he was great at being able to get religious right votes and helped his father win, a lesson he learned well.
This is why as President he'd do things like have biblical phrases put in speeches that most wouldn't notice but the religious right would recognize and appreciate.
