51% favor Bush impeachment?

Wonkette argues that This Newsweek story, specifically the polling data on page two support a conclusion that 51% of Americans favor Bush's impeachment. Here's the relevant part of the Newsweek poll:

Other parts of a potential Democratic agenda receive less support, especially calls to impeach Bush: 47 percent of Democrats say that should be a “top priority,” but only 28 percent of all Americans say it should be, 23 percent say it should be a lower priority and nearly half, 44 percent, say it should not be done. (Five percent of Republicans say it should be a top priority and 15 percent of Republicans say it should be a lower priority; 78 percent oppose impeachment.)

I've added emphasis to two portions. From the bolded text, we get that 28+23=51 percent of all Americans think that Bush impeachment should be a priority. From the italicized text, we get that 5+15=20 percent of Republicans, even, think that the Bush impeachment should be a priority.

That's a lot of people who really do not like George Bush. Clinton, who actually was impeached, enjoyed far more popular support. The majority of Americans consistently opposed the Clinton impeachment. (source, source). And during the impeachment, and in fact throughtout

Furthermore, during the time period covered by the impeachment scandal, Clinton's job approval rating never dropped below 50%. Bush is much less popular. The last time Bush's job approval rating was as high as 50% was May of 2005, more than a year ago. Bush has been hovering around a 40% approval rating this year, and hasn't even seen the Olympian heights of a 40% mark this month.
