Some non-Christians feel left out of election

DALLAS (Reuters) - In a U.S. election campaign where presidential candidates from both major parties have talked openly about their Christian faith, some non-Christians feel shut out or turned off.

Despite the constitutional separation of church and state, religion plays a big and sometimes decisive role in politics in America, where levels of belief and regular worship are far higher than those in Europe.

"Non-Christians are concerned that they will be excluded from the process," said Ahmed Rehab, a spokesman with the Council on American-Islamic Relations.

"I welcome faith values if they inspire candidates to do good things. But I worry if it is used as a litmus test to include someone in political participation."

About 75 percent of the U.S. population, long a melting pot of immigrants from around the world, identifies itself as Christian, according to several estimates.

That is a huge but divergent source of potential votes for Republican and Democratic candidates in their long contest for the nomination to run for the White House in the November election.

U.S. politicians are not shy of talking about their religion and regularly appear in church.

In recent decades, part of the American political drama has been scripted by the "religious right" -- mostly white evangelical Protestants united by strong opposition to abortion and gay marriage who have been a key base of support for the Republican Party.
