Boehner Won't Back Down: NJ’s THE EDGE—Brought to you by the American Petroleum Institute

TODAY IN ONE PARAGRAPH: The House is back with a vengeance today, with Speaker John Boehner warning that Republicans won't simply go along with the Senate's bill to extend the federal budget but leave Obamacare untouched, and promised the GOP will continue to demand policy concessions in exchange for signing off on a budget deal. House Republicans also mapped out their strategy on the upcoming debt-ceiling debate, where they're promising to take another crack at defunding Obamacare, forcing approval of the Keystone XL pipeline, and scoring other policy objectives. Elsewhere, the administration announced another delay to implementing Obamacare—moving the enrollment date in most small-business exchanges to November—while Texas state Sen. Wendy Davis signaled her plans to run for governor.

HAPPENING RIGHT NOW: Harry Reid is asking for the Senate to accelerate the timetable for a cloture vote on the budget resolution, hoping to move votes to Wednesday and Thursday rather than the previously expected schedule of votes Friday and Saturday. Utah Republican Mike Lee is objecting. (Watch on C-SPAN

TOMORROW IN ONE PARAGRAPH: Assuming Reid is unable to get the timetable accelerated to this evening, the action heads back in the Senate on Friday morning, when the chamber is scheduled to undertake a pivotal cloture vote on an extension of the soon-to-expire federal budget. If Harry Reid can clear the 60-vote hurdle for cloture, he'll have a clear path to passing a budget extension that does not affect funding for Obamacare. Mitch McConnell and other Republican senators have said they won't stand in Reid's way on cloture, but Sen. Ted Cruz is demanding his fellow Republicans do everything they can to keep Obamacare from being funded—and promising to make them pay politically if they don't. The cloture vote is set for the morning, while final passage of the bill is likely to come Saturday.
