Democratic Rep. Dan Boren, Oklahoma's only Democratic member of the congressional delegation, has refused to endorse Sen. Barack Obama for presidential office.

However Boren has said the Illinois Senator will have his vote both at the Democratic convention in Denver in August and in November on election day.

Calling Obama "the most liberal senator in Congress", Boren criticised his record on working with Republicans saying "it does not reflect working in a bipartisan fashion" and has joined Florida Rep. Tim Mahoney in refusing to endorse the presumptive Democratic nominee.

Mitt Romney, the former contender for Republican presidential nominee and suggested running mate for presumptive Republican nominee John McCain, has declared he has had no discussions with McCain over the VP position.

Romney told delegates at the Colorado Republican Party's state convention that though the Arizona senator wasn't his first choice for president (he himself was), he was happy to do all he could to assist him reach that goal.

The former Massachusetts governor along with two other running mate contenders, Florida Gov. Charlie Crist and Louisiana Gov. Bobby Jindal have also met with the Arizona senator recently.
