WASHINGTON (AP) — Foes from left and right are using the delayed vote on the Republican health care bill to make it as politically toxic as possible for wavering GOP senators to support it.

But the postponement also gives Majority Leader Mitch McConnell and the White House more time to cut the deals they need to rescue the imperiled measure.

McConnell signaled Monday that days of bargaining and persuasion with reluctant colleagues lay ahead. He says the only way to prevail "is with continued hard work, and that's just what we intend to do. "

The AARP is aiming TV and radio ads at undecided, moderate Republican senators in five states. From the right, Americans for Prosperity is rallying its members to urge senators to make the bill even more conservative.
