(CNN) -

West Virginia Gov. Earl Ray Tomblin, a Democrat, said in an interview published Wednesday he's unsure if he'll vote for President Barack Obama in the upcoming general election.

Tomblin is the second prominent Democrat from West Virginia to express doubts about voting for Obama. Sen. Joe Manchin said in mid-April he may not cast a ballot for Obama in November, citing the effect the president's economic policies have had on his constituents.

In an interview with the Charleston, West Virginia, "Daily Mail," Tomblin expressed similar concerns.

"President Obama has apparently made it his mission to drive the backbone of West Virginia's economy, coal and the energy industry, out of business," Tomblin said. "That will not only hurt thousands of West Virginia families, it will destroy the economic fabric of our state."

Mitt Romney, Obama's likely GOP rival in the general election, would also enact policies harmful to West Virginians, Tomblin said.

"His policies will put more burdens on West Virginia families who are simply trying to make ends meet," Tomblin said of Romney.

Manchin and Tomblin are Democrats in a largely conservative state - West Virginia last voted for a Democrat in a presidential election in 1996. Both politicians have staked out independent positions that often put them at odds with other members of their parties.

Manchin was one of about a dozen Democrats to side in a March vote with Republicans on the Keystone XL pipeline. He voted against both parties' bills to raise the federal government's debt ceiling in the heated showdown last summer.

Tomblin bucked Obama in March by suing the Environmental Protection Agency over a new rule he says inhibits jobs creation by putting restrictions on coal mining, one of the state's largest industries.

Tomblin won a special election in October to replace Manchin as West Virginia's governor. Manchin himself won a special election to replace the late Sen. Robert Byrd, who at the time of his death was the longest serving member of Congress in history.

Both Tomblin and Manchin face re-election in November for full terms in their respective offices.

A spokesman for Tombin's re-election campaign said the governor was "absolutely" still a Democrat.

"He was expressing an opinion when asked," Chris Stadelman said.
