This week in Washington, House Republicans will try to produce a little political heat from rising energy prices. They will attempt to block Congress from adjourning for its summer recess if Democrats don’t allow an up or down vote on the GOP energy plan, which includes expanded drilling in the Outer Continental Shelf (OCS). House procedures — which heavily favor the majority party — will allow the Democrats to thwart those efforts, but Republicans can claim the issue: Congress will leave town without an up or down vote on expanded OCS drilling. Republicans hope movement in public opinion in favor of offshore drilling, spurred by record gasoline prices, will produce a new and effective line of political attack. The GOP hypothesis draws some support in at least one Senate race. Former Republican Congressman Bob Schaffer has made progress in his contest against U.S. Rep. Mark Udall in Colorado, according to the most recent polling. What accounts for the GOP’s recent improvement? It’s gasoline prices – and more specifically, the stark differences between the two candidates on drilling policies. Voters apparently now see a much clearer connection between extreme environmental policies – like banning all offshore drilling – and pain at the pump. The last two independent polls show the race moving from about a 10-point Udall advantage to a near dead heat. The Rasmussen numbers show a particularly strong shift among swing voters: “Among unaffiliated voters, Udall leads by just four percentage points. A month ago, he held a twenty-one point lead among these voters.” You can read the full Rasmussen Colorado poll report here. This piece in today’s Washington Times underscores how Republican Schaffer has transformed his support for drilling from a political liability to an electoral asset. Record gasoline prices linked with what House Republican leader John Boehner calls the “Drill Nothing Congress” could fuel the political engines of many Republican congressional candidates this fall.
