* Jeff Zeleny has a fascinating glimpse into Obama’s deepening involvement in his own reelection effort, and his conviction that a loss will dispatch his first term accomplishments to history.

* Mitt Romney’s next attack on Obama, courtesy of a Romney aide:

The Romney campaign is planning to seize on Obama’s “not coming to grips” with the reality of his record, an aide said, seeing an opening to paint Obama as someone unwilling to take responsibility — something Romney will say would be unacceptable in the private sector.

* Brad Plumer on how declining labor force participation is masking the severity of unemployment, and on how GOPers are oversimplifying things with their “people quitting the Obama economy” talking point.

* Jonathan Chait is blunt: The economy is weak, but it isn’t weak enough for Romney to beat Obama. For now, anyway.

* Steve Benen’s regular Friday tally of Mitt Romney’s most glaring falsehoods and distortions of the week weighs in at a whopping 18 items.

* Obama re-elect reality check of the day:

The number of black and Hispanic registered voters has fallen sharply since 2008, posing a serious challenge to the Obama campaign in an election that could turn on the participation of minority voters.

Dems say Obama’s campaign will have the time and resources to fix the problem. Still, a trend worth watching.

* Relatedly, Ron Brownstein takes you inside the raging debate over whether muffled Latino turnout and unexpected demographic shifts will damage Obama’s reelection prospects.

* Funny point from Ed Kilgore: Romney’s best hope for making inroads among Latinos may not be a running mate who’s good on immigration, but one who isn’t actively anti-immigrant.

* Nate Silver runs the numbers and finds the odds for blocking anti-gay Amendment One in North Carolina are slipping away, with only four days to go.

* Elizabeth Warren’s campaign sinks another $800,000 into that ad showing Obama trumpeting her as a fighter for the middle class, a sign she really needs to get back to what this race is supposed to be about.

* Striking: “A new Howey/DePauw Indiana Battleground Poll shows Indiana state Treasurer Richard Mourdock with a ten-point lead over Sen. Dick Lugar in the state’s May 8th Republican primary.”

A Mourdock win would increase Dem odds, but by most accounts the GOP would still be the slight favorite.

* Michael Cohen offers a compelling reason why Obama is touting the Bin Laden killing: It’s absolutely essential to his reelection, which turns on his need to shore up leadership qualities amid a bad economy.

* Brian Vastag has the full story of Heartland Institute’s experiment in comparing climate believers with mass murderers, and you’ll be surprised to hear that other climate “skeptics” thought this might not be politically wise.

* The New York Review of Books has an extract from Paul Krugman’s new book that pillories the commentariat’s blinkered view of what the public actually wants in the way of economic policy: Results.

* And this, from Rachel Weiner’s piece on how the Ric Grenell mess has boxed in Romney, is amusing:

The former Massachusetts governor is now forced to insist that he didn’t fire an aide for his sexuality, an assertion that could jeopardize his already shaky relationship with the religious right.

The guy’s gone, but it’s still a liability that Romney isn’t publicly humiliating him, too?

And what else?
