Statistics are not giving Democrats much reason for happiness these days.
Gallup's latest update on 2010 congressional voting preferences finds 50% of  registered voters saying they would vote for the Republican candidate in their  district, and 43% for the Democratic candidate, if the elections were held  today. Republicans have led in each of the past three weeks, and their current  50% vote share and seven percentage-point lead represent their best showings  thus far in 2010.
That’s  the biggest lead for Republicans ever measured in the 60 years Gallup has been  taking this poll. Further, this poll question has a history of understating  Republican support in the past. In August of 1994, a year when Republicans  made historic electoral gains, Democrats were actually  ahead in Gallup’s generic poll.
As he attempts to shepherd the U.S. through the  sluggish economic recovery and galvanize Democratic voters ahead of a  congressional election cycle in which the party is expected to sustain heavy  losses, Obama's approval rating has held 
relatively steady, at a near even split: 46% of respondents  back his job performance, with 45% expressing disapproval. Voters are far less  enthusiastic about the President's policies, however, with 57% asserting that  the U.S. is headed in the wrong direction.
 That wasn't the only grim news for Democrats. The  GOP has snatched the lead in generic congressional balloting, with 43% of likely  voters saying they would vote for a Republican candidate if the midterm  elections were held today, compared with 37% for Democrats. (Last month, Democrats held a slight edge in generic balloting,  43%-42%.
 
The Washington Post reports economic data foreshadowing greater problems ahead:
Unemployment is in this country is going the wrong way.
This morning, the Labor Department said that new jobless claims filed last  week unexpectedly  rose by 12,000 to hit 500,000, the first time since November that the  half-million mark has been reached. The four-week moving average of new  unemployment claims, which smooths out week-to-week volatility, rose by 8,000 to  482,500. Forecasters expected last week's new jobless claims number to go down,  not up...Today's number marked the third straight week of increase in new weekly  jobless claims. That suggests that employers not only are not hiring, it  suggests that they're starting to lay off workers again, and that will start a  whole cascade of problems for the U.S. economy and the politicians in Washington  who face reelection this November.
And to top it off, the Pew Center for the People and the Press has these data:
The religious landscape is far more favorable to Republicans than was the case  as recently as 2008. Half of white non-Hispanic Catholics (50%) currently  identify with or lean toward the Republican Party, up nine points since 2008.  Among religiously unaffiliated voters, who have been stalwart supporters of  Democrats in recent elections, 29% currently identify with or lean toward the  Republican Party, up from 25% in 2008 (the proportion identifying as Democrats  has fallen seven points since then). And 33% of Jewish voters identify with or  lean toward the Republican Party, up from 20% in 2008.
