President Barack Obama implored voters on Saturday to resist a Republican tide, warning that if the GOP prevails in Tuesday's midterm elections all the progress of his first two years in office "can be rolled back."

That would be just fine, said Rep. John Boehner, in line to become the new speaker if Republicans take the House, as expected. He declared, "Americans are demanding a new way forward in Washington."


Embarking on a four-state weekend campaign dash, Obama acknowledged the difficulties Democrats face - the distinct chance of losing their comfortable majority in the House and possibly the Senate, as well as several governors' seats.


All four weekend stops are in states Obama carried in 2008 - Pennsylvania, Connecticut, Illinois and Ohio. But Democratic candidates for the Senate, House and governorships are struggling in these places and elsewhere, and Obama is making a last-ditch plea for the party's core supporters not to abandon them.


"It is difficult here in Pennsylvania, it is difficult all across the country," Obama told several hundred campaign volunteers at Temple University in Philadelphia, a Democratic-leaning city he has visited often.
