U.S. Rep. Dan Webster’s stance on the federal government shutdown is putting the Winter Garden Republican's district in political play next year, according to a new Democratic-leaning poll.

The MoveOn.org-commissioned poll surveyed 24 swing districts and found 17 where the Republican incumbent runs behind a generic Democrat after voters are told the GOP member voted to shut down parts of the federal government to block funding of Obamacare.

Webster's seat would be one of those, the group claims. Right now, he's just a point down -- 45 percent to 46 percent -- against a generic opponent. 

When told Webster "voted to support shutting down major activities of the federal government as a way to stop the health care law from being put into place," 52 percent say they are less likely to vote for him, while 37 percent said they are more likely to back Webster. The rest don't care or are not sure.

Once they know that stance, the Democratic challenger edges Webster by 49 percent to 44 percent.

Here's the results of the early October Public Policy Polling survey of 768 voters from that Central Florida district.

If the 2014 elections were held today, those results could mean Republicans could lose control of Congress, the group said.

Tea Party Republicans have gone too far with their government shutdown,” the liberal group says.

The poll is surely designed to pressure GOP members to back off the push to defund Obamacare. And there's a world of politics that could play out in the next few months that could make the shutdown a distant memory -- or the driving issue next fall.

But future polls like this could spur Democrats to put a real challenger up against Webster.

Former police chief Val Demings lost to Webster in 2012 by a respectable 52-48 percent margin, but that was in a year when President Obama topped the ticket, and presumably gave Demings a boost.

In 2014, no such Democratic superstar is likely to top the ticket. So while Demings is interested in another run at Congress, she's also been considering a 2014 run for Orange County mayor.

That race poses another daunting challenge, though. Toppling incumbent Republican MayorTeresa Jacobs would be an uphill fight, as well.

Webster has made no bones about his votes in recent weeks to cut spending and defund Obamacare. But like other Republicans, he's blamed Democrats for the shutdown.

After his first major vote on this fight, on Sept. 20, Webster's office released this statement:

"I supported legislation that continues our effort to control reckless spending, defunds Obamacare and prevents a government shutdown. This House-passed funding measure rolls back spending to pre-2008 spending levels while halting the unworkable health care policies contained in Obamacare that raise costs, limit choices and destroy jobs. It is time for the Senate to join us and pass this legislation without delay."
