Rockefeller won re-election easily in 2008 over Republican Jay Wolfe with 64 percent of the vote.
But it was a big Democratic year and Wolfe was a little known and underfunded opponent.
A more formidable Republican could give a much closer race in 2014, especially if a Democratic purge is still underway.
Of course, Rockefeller still has a lot going for him.
You don't serve as long as Rockefeller has and not accumulate some diehard party support.
Rockefeller may not be Robert Byrd in terms of inspiring straight-ticket voters, but there are loyal Dems who would pass on Obama and make sure they voted for Rockefeller.
Rockefeller's considerable wealth is often cited as a deterrent to opponents, but Rockefeller stopped spending his own money several elections ago.
He was taking too much heat from critics who accused him of "buying" elections. But as a veteran senator and the favorite to win re-election, he will have no problem raising money.
2014 is a long way off. Lots can happen, lots will happen before the election.
Today's poll numbers are just a snapshot of the moment.
Finally, Rockefeller may not have a significant opponent. One of the challenges of the Republican Party in West Virginia has been coming up with viable candidates.
Shelley Moore Capito's name comes up frequently, but she hasn't made her plans known yet. Rockefeller could get a pass in 2014.
PPP's Tom Jensen believes the GOP could skip the Manchin race in 2012 and look at the Rockefeller race two years later.
"If Republicans want to pick up a Senate seat in West Virginia, it looks like they'll have a much better chance in 2014, whether Rockefeller runs or not, than they have next year."
So it's good to be Rockefeller, but he would be wise to keep looking over his shoulder while calculating how much the support of President Obama is going to cost him.
