London, Oct 26 : With the Democrats poised for gains in the Senate and the House, moderate Republicans fear a wipeout that would leave their party in the grip of evangelicals increasingly out of touch with the public.

Some Republicans believe John McCain should adopt a more positive approach to campaigning, the Guardian reported.

Voting for a Republican president runs in the blood of places like Gainesville. The pretty little town of 15,000 sits in north Texas ranch country and it is safe to say that Barack Obama has few fans here.

Certainly Jim Farquhar, who works in the justice system, has taken to heart warnings that Obama has links with dangerous radicals, such as former 1960s militant Bill Ayers.

''Obama scares me. He has all these friendships. You just don''t know how that might effect him once he gets into office,'' Farquhar said as he stood outside Gainsville''s sturdy old courthouse. ''I''m voting for John McCain.''

Such worries are increasingly not shared by many other Americans. Weeks of relentless attacks on Obama by McCain and his running mate Sarah Palin have not succeeded in denting Obama''s lead.

Instead it has strengthened. Across America, battleground states such as Ohio and Pennsylvania are falling into Obama''s column and southern states such as Virginia and North Carolina are going from red to blue. Some Democratic insiders are even whispering about the prospect of a landslide.

The flipside of that is a potentially devastating Republican loss. If current polling holds true, the party may be reduced to its core support in the solid red heartland that runs through Texas, Oklahoma, Alabama, Georgia and other southern and western states.

That would trigger a profound crisis for a party that just three years ago was basking in the afterglow of a convincing presidential win and dreaming of creating a ''permanent majority''.

Now that same Republican party could face a prolonged period in the political wilderness, working out how to appeal to an American public that seems prepared to send a pro-life, black senator from Chicago to the White House and reject a conservative Republican war hero. (ANI)
