Poll after poll shows President Obama's approval rating dipping recently, and one new Quinnipiac University Poll finds that voters say Mitt Romney would have been a better choice in 2012.

With Mr. Obama deploying military troops to Iraq, failing to find compromise with Congress and seeing major defeats in the Supreme Court, voters continue to sour on him.

Quinnipiac found 45 percent of voters say the country would have been better off if Mr. Romney, the 2012 GOP nominee, had been election, while just 38 percent say Mr. Obama remains a better choice.

Even Democrats aren't so sure — just 74 percent of them told the pollsters Mr. Obama was clearly the better pick in the last election.

Voters also rate him the worst president since World War II, topping even his predecessor, President George W. Bush, who had left office with terrible ratings.

If a poll released today is any indication, voters in New Jersey have slightly soured on President Obama.

About 51 percent of New Jersey voters surveyed last week disapprove of Obama's performance, according to the Monmouth University/Asbury Park Press poll. Another 45 percent approve of the work he's doing.

That's a downturn since April, when the president had a 49 percent approval rating; 47 percent gave him a thumbs down at that time.

Democratic Sen. Cory Booker has the early lead in New Jersey's U.S. Senate race, but a poll shows uncertainty among voters.

Today's Monmouth University/Asbury Park Press Poll finds 43 percent of registered voters surveyed support Booker compared to 23 percent who back Republican Jeff Bell.

However, 15 percent say they would vote for another candidate and 17 percent are undecided.

Poll director Patrick Murray says the early preference for none of the above indicates a simmering distrust of the two major parties.

Booker's approval rating of 48 percent remains mostly unchanged from previous surveys in April and February.
