With the Senate likely to house 60 desks on the Democratic side of the aisle before too long, an emboldened majority in the House after winning some intra-party skirmishes like fast-tracking health care reform and an inter-party victory in upstate New York, and a cratering Republican Party still searching for a path back to power, Obama enters this next phase of his presidency in an envious position and one of a considerable strength.
But he acknowledged that even with Sen. Arlen Specter's party change, he still faces challenges from senators who "have very strong opinions" he said.
"Now, I am under no illusions that suddenly I'm going to have a rubber-stamp Senate. I've got Democrats who don't agree with me on everything, and that's how it should be," Obama said.
So, what will Obama use his 69 percent approval rating to accomplish? Political observers will be disecting the president's press conference to determine whether he is deciding to put that political capital on the line or if he intends to keep most of his legislative battling ahead behind closed doors.
Leadership aides on Capitol Hill anticipate that perhaps the biggest White House push will come on healthcare reform that includes a public option, a component that is of great concern to the insurance industry which Obama hopes to keep at the negotiating table throughout the legislative process in order to avoid a 1994-style blowup.
One new role Obama is expected to play as he heads into his next 100 Days is that of fundraiser-in-chief. The president has already headlined two fundraisers for the Democratic National Committee where he helped collect nearly $3 million.
He also e-mailed supporters about his endorsement of Scott Murphy, the new Democratic congressman from upstate New York. Other than that toe-dipping, Obama has shied away from pure politics.
But Specter's party switching 100th Day gift to Obama kicked off what is expected to be a more overtly political phase of his presidency as he helps to bolster Democratic bank accounts in advance of next year's midterm elections.
After attempting to clear the Pennsylvania Democratic primary field with his and Joe Biden's endorsement of Specter this morning, Obama is also scheduled to shake the money tree for Senate Majority Leader Harry Reid, D-Nev., at the end of next month in Las Vegas.
The two Democratic campaign committees on Capitol Hill have announced the president will be headlining a June 18 fundraiser in Washington, D.C., to help fill their midterm coffers.
As he takes on that more partisan task, the president will strive to strike the balance of party leader without tarnishing his current strong support from the key ideologically centrist Americans.
