WASHINGTON – Who will be blamed if Republicans in the U.S. House of Representatives get crushed in Tuesday’s election?

That’s a question being asked amid Republican fears that they may lose as many as 30 seats. That would be on top of the 30 they dropped in the 2006 election that saw Democrats win control of the House, which they now hold, 235-199.

If House Republicans have another bad night, their leaders could be in jeopardy of being replaced — just like the manager of the baseball team who’s bounced after a bad season or two.

“There’s going to be a shakeup,” predicted a senior Republican leadership aide.

A former leadership aide said another big loss would trigger “spontaneous combustion from the House Republican” members, signaling “a need for change.”
