WASHINGTON (CNN) - Senate Majority Leader Harry Reid may put some of the Democratic presidential candidates in awkward spot this weekend.
The Nevada Democrat told reporters Thursday he will schedule a Senate vote on the Energy Bill this Saturday. The bill, which calls for a fuel economy standard of 35 miles per gallon by the year 2020, passed the House earlier Thursday by a vote of 235-181.
But the vote is expected to be considerably tighter in the Senate, where Republicans have threatened to filibuster the measure and Reid may need to muster at least 60 votes to block that action. To that end, Reid said he has asked the four Senate Democrats running for president – Joe Biden of Delaware, Hillary Clinton of New York, Barack Obama of Illinois and Chris Dodd of Connecticut – to head back to Capitol Hill Saturday.
But with less than a month to go until the Iowa caucuses – and no clear frontrunner – Reid may have hard time getting the candidates back inside the Beltway.
Obama especially will have a difficult time making the trip to Washington. He and talk-show host Oprah Winfrey are set to make a highly anticipated tour through the Hawkeye State Saturday before heading to South Carolina together on Sunday.
The Senate offices of two of the presidential candidates say they have been told a Saturday vote is only a possibility. So far, none have said they plan to return to Washington that day.
