Washington (CNN) – Is Washington a holy city? It might seem that way, with all the talk about religion and morality in the 2012 election.

But all that God talk may be rubbing voters the wrong way.

"It's getting ugly out there," said Tim King, an evangelical Christian who works for the progressive religious group Sojourners. "There are a lot of Christians who are using their faith as a political weapon, which it's never meant to be."

King, who calls himself "politically homeless," says that while both parties talk about faith and invoke Scripture, he and other young evangelicals he knows sense an undercurrent of political gamesmanship in all the religious talk.

"You don't get to win the argument because you have more Bible verses," he told CNN Radio. "You need to make the case about why your policies are good for everyone."

King is part of what looks like a national shift. In March, the Pew Forum for Religion and Public Life saw a first in its ten years of polling: the largest group of voters in its survey, 38%, said that politicians are talking about religion "too much" right now.

"In fact, we saw an all-time high number of people taking that view," said Greg Smith, one of the researchers who produced the Pew report.

The survey found that 30% of Americans think politicians talk "too little" about faith and that 25% said it's the "right amount."

There is a political factor, with twice as many Democrats saying politicians talk too much about religion as Republicans. But both parties saw sharp increases in the number of voters who want to hear less about religion from politicians.

Religious talk played a big role in recent elections, with Barack Obama distancing himself form his longtime pastor in 2008 and George W. Bush benefitting from a surge in so-called values voters in 2004.

“I think morality is being talked about a lot more in 2012," said David Brody, chief political correspondent for the Christian Broadcasting Network.

"Not necessarily religion, but now we've seen the budget cloaked in moral terms by Roman Catholic (Congressman) Paul Ryan and by Catholics who think he's wrong, on moral grounds," he said. "Immorality has been invoked a lot more in 2012."

Brody noted another possible factor, saying that many voters question the sincerity of how some candidates talk about faith.

"There are some (politicians) who are natural when they talk about faith," Brody said, "there are other politicians who may do it more for political purposes."

For now, it seems that the more politicians talk about religion, the more voters want them to stop such talk.
