TAMPA, Fla. – Patton Boggs partner Benjamin Ginsberg is facing a growing storm of criticism from Republican delegates who say he pushed through a rules change that would help Mitt Romney if the presumptive GOP nominee ousts President Barack Obama and seeks reelection.

Ginsberg, who serves as the Romney campaign’s top lawyer, led the effort to insert language into a rules committee report that would allow presidential candidates to select their own delegates in states they carry, stripping away a power that the state Republican parties hold, according to members of the rules panel. But a group of delegates plan to present amendments that would eliminate Ginsberg’s alterations before the report goes up for a final vote on Tuesday.
