Over the weekend, bloggers were buzzing about yet another flip flop from Barack Obama: He now will support the House FISA compromise bill, even though he didn't back in February.

Obama said he will support the FISA compromise, which Politico's Ben Smith explains "offers retroactive immunity to telecommunications companies who helped the government listen in on American citizens--which Obama says he'll fight to remove from the legislation--and expands legal wiretapping powers. Obama praises it for restoring a legal framework and judicial oversight to the process." He claims that he will "try" to strip telecom immunity from the bill.

The Washington Post's Paul Kane notes that "Obama sought to walk the fine political line between GOP accusations that he is weak on foreign policy--Sen. John McCain (R-Ariz.) called passing the legislation a 'vital national security matter'--and alienating his base." But bloggers on both sides of the aisle just think that Obama is a typical opportunist politician.

On the right, Power Line's Paul Mirengoff says, "Obama is a default hard-leftist with a streak of opportunism as big as all outdoors." Hot Air's Ed Morrissey asks, "Does Obama support this FISA reform bill or not? Will he try filibustering a bill that won a large majority in the House and which is even more of a compromise than the bill that won 68 votes in the Senate in February? Will Obama try to do yet another flip-flop and still convince people that he has any principles at all?"

And on the left, Glenn Greenwald seems to agree: "Obama has obviously calculated that sacrificing the rule of law and the Fourth Amendment is a worthwhile price to pay to bolster his standing a tiny bit in a couple of swing states." And so does Talk Left's Big Tent Democrat: "I always knew Obama was just a pol." Meanwhile, Daily Kos blogger Hunter is insulted.

Redstate's Moe Lane has some advice for these scorned bloggers: "I want progressives to email the Senator and demand that he filibuster: he'll either not do so, and thus betray them further; or he'll cave to them, which will embarrass the Democratic Party at the very moment that they need to show Unity. And either way, the FISA bill still passes."
