Bloggers begin the last big Democratic primary day with a pair of exclusives that raise questions about Hillary Clinton's viability in North Carolina and John McCain's Republican loyalties.

It's "Danger Day" for Hillary Clinton, according to Drudge Report, which speaks to a "top campaign official" who worries that Clinton will lose by 15 points to Barack Obama in North Carolina. The flash, however, also notes that the campaign team is working to lower expectations. But Clinton-supporter Jerome Armstrong sees hope for Clinton in both primaries Tuesday, as she's been able to pick up undecided voters in the final days of recent contests.

Obama backers need to remember that the contest isn't over yet, since both candidates need the superdelegates, reminds Armstrong's colleague Todd Beeton. kos counters Clinton's electability argument by noting polls showing Obama would have fewer states to defend and more states he could capture. One of those superdelegates, John Edwards, told People magazine that he and his wife won't endorse during the primary and that they like Clinton's tenacity and Obama's call for change but dislike her "old politics" and his lack of substance.

In the other big exclusive of primary day, Arianna Huffington reports that McCain once told her he didn’t vote for George W. Bush in the 2000 general election, a decision that Huffington contrasts with the senator's laudatory comments toward Bush since then. But both Allahpundit and Ed Morrissey at Hot Air believe the revelation could help McCain with independents.

It's McCain's 2008 positions that cause concern among conservative bloggers. McCain risks their support if he doesn't end his renewed support for comprehensive immigration reform, Morrissey writes. He shouldn't speak before the National Council of La Raza, since it appeals to a "sort of Hispanic racialist pride," according to Victor Davis Hanson. And he's wrong to back a cap-and-trade system to reduce greenhouse gas emissions, since it calls for mandated emissions reductions, says Jim Manzi.

Turning to Congress, RedState's directors endorse conservative Republican Tom Rooney in Rep. Mark Foley's (R-Fla.) old seat, where Republicans think they can take out Rep. Tim Mahoney (D) in a district that has traditionally gone to a Republican. And mcjoan at Daily Kos gives some unexpected props to Sen. Joe Lieberman (I-Conn.), who has concerns about the civil liberties and privacy implications of a new Department of Homeland Security program.
