The Des Moines Register released results from a poll that shows Barack Obama would win Iowa in the general election against John McCain. However, the poll shows McCain would win in a matchup against Hillary Clinton.

Obama 53%
McCain 36%

Clinton 40%
McCain 49%

 
These results are similar to Survey USA's poll released earlier in the week.

The most interesting thing from the Des Moines Register poll was Obama's strength throughout the entire state of Iowa and among woman voters.

Other good news in the poll for Obama includes a decided advantage among female voters, who preferred him over McCain by a margin of more than 20 percentage points.

Obama also beats McCain in each of Iowa's five congressional districts, including the GOP-heavy 5th District in western Iowa. Obama also pulls more support from the opposing party than either of the other two candidates, with 14 percent of Republicans saying they would vote for him.

These numbers show that Obama would help Democratic candidates up and down the ballot. Having Obama on the ballot would be a boost to Congressional candidates in Iowa's 4th and 5th Districts and help Democrats get a larger majority in the Iowa House.
