OnSight/Keating Poll: Obama Leads In Colorado By 4 Points In First Poll Since Romney Announced Ryan Pick

A new poll released Friday from OnSight Public Affairs/Keating Research gives President Barack Obama a four-point lead over GOP challenger Mitt Romney in Colorado.

This is the first poll of Colorado voters since the announcement of U.S. Rep. Paul Ryan joining the Romney ticket and it appears there has not been a Ryan bump for Romney in the Centennial State. The poll also arrives in the wake of an Electoral College prediction model announced this week from two professors at University of Colorado that points to a Romney win in 2012.

Of the 500 likely Colorado voters OnSight/Keating surveyed, 48 percent said they would vote for Obama while 44 percent said they would vote for Romney, if the election were held today.

The Huffington Post's Pollster estimate, which currently tracks 16 polls including the OnSight/Keating poll, shows a tight race with Obama leading Romney in Colorado by a slimmer margin, 47.9 percent to 46 percent.

Nationally, the race appears even tighter with the Pollster average of 407 polls giving Obama a lead over Romney by less than a percentage point, 46.4 percent to 45.5 percent as of Friday.

"Clearly, Romney’s choice of Ryan as his running mate has not provided an impact on the Presidential race in Colorado,” said pollster Chris Keating in a statement. “But this is a close race that remains just within the margin of error. There is no doubt that the Presidential race in Colorado will depend on voter turnout."

According to OnSight, Obama's advantage in Colorado stems from strong support from women and Hispanic voters -- Obama leads Romney by 10 points among women (51 percent to 41 percent) and that lead increases to 15 points among younger women. Hispanic voters overwhelmingly support Obama -- according to the poll, Obama leads Romney among Hispanic voters by staggering 33 points (65 percent to 32 percent).

However Romney did lead Obama among Colorado men by three points (48 percent to 45 percent) and maintains a one-point lead among whites with 47 percent.

The poll from OnSight, a Democratic group whose founding partner Mike Melanson managed the campaigns of both Governor John Hickenlooper and Senator Mark Udall, was based on a 500 live telephone interviews conducted August 21-22. Read the full poll results and question wording here.
