WASHINGTON - Two prominent Bay State Democrats questioned President Bush's leadership style yesterday, cracking the veneer of bipartisan unity Congress has shown in the wake of the twin terrorist attacks.

``It's not a question of what he's saying,'' said U.S. Rep. Richard Neal (D-Springfield). ``The content is fine. But the blandness with which it is delivered has caused considerable reaction.''

U.S. Rep. Martin T. Meehan (D-Lowell) scoffed at reports Air Force One was targeted by terrorists - the reason Bush aides have put forth to explain why the president delayed his return to Washington after Tuesday's attack on the Pentagon. ``I don't buy the notion Air Force One was a target,'' said Meehan. ``That's just PR. That's just spin.''
